today the „Blue“->LINK ES9038Q2M arrived; first impressions:
the pcb is much more light (in weight) than the ones before..
first musical impressions were:
wider soundstage..heavy „lock“-problems with the Skysong-XMOS-USB-bridge (guess its a firmware/driver issue (had to wait for an update or so); i use here right now a Samsung BluRay-player directly via coax), but absolutely more „pop“-tune, by far not so analytic, spacious, also very „flat“, cries really out for a „Muses02“ OP-Amp..
there is absolutely something missing->guess it really needs its 15V..(this one is only with the 12V-plug)(but i could feed it maybe also with 15V->have to check/ask the seller)
have immediately changed to „Muses02“; which i normally don´t do in fresh, new hifi-gear..(1-2 days „play in“-time)..
the HW-control with a 10k pot was also not so promising as expected..
i didnt test the 7 different filter; maybe the „devil“ is there..
also it could be the pcb (and the soldered components itself); don´t know it at present->more to come..
Conclusion for now (and dont forget, this is „whining on a high level“ 😉 ):
more „pop-sound“ (originally the ES9038Q2M is/was made for handys/portables), not so analytic, spacious, needs apparently its 15V (+/-), cries out for another Op-Amp (Muses02 here), didnt test the filter right know; maybe its also the quality of the pcb/components..)(but that are only the first impressions, can change without notice 😉 )
(Update 2: so, got halfway at least a fairly accurate sound..(its not sooo bad/but for me it still sounds like plate/sheet 😉 )). This ES9038Q2M is very good with a Raspberry (via I2S); no clicks/pops/distortions anymore..very easy !! i use here now DietPi V6.0->tried „sabre-k2m“; didnt work..“hifiberry-dac“+“rpi-dac“ works without any problems (but only up to 24/192; as said, „our old problem“; need modified kernel..)
as said, on a pi now very easy to handle, no clicks/pops etc..sounds very well but not soo „HiFi“ as with the ES9018/28..somehow less distorted/cleaner in a way, but not so transparent/spacious as the „old“-sabres..could be a problem with the pcb/components on it..but for normal user this ES9038Q2M should be enough 😉
(by that for me DietPi V6.0 is at present much better/cleaner than Moode V4..its much „nearer“ to the original recording; with this Dietpi u can fairly begin to work it out/fine tune))
(Update 1: (Win+Skysong USB-bridge)absolute no comparison to my „old“ ES9018K2M+ES9028Q2M->they sound really much better, absolutely more Hifi; dont know what the main reason could be; maybe the pcb+the components; absolut „platy“; sounds like sheet/plate..
(Raspberry I2S Moode 4.0 („hifiberry-dac“)); sounds really better on a raspberry !! absolutely easy to use; no more such horrible clicks/pops changing files/bitrates..as made for it 😉 ->used the hifiberry-dac „overlay“->absolut no problems up to 192/24bit, but no more (our „old“ problem..) try to use some other overlays meanwhile..
settings->“Audiophonics ES9028 DAC“ works too (in Moode V4->but only up to 192/24)
see at the top line..
must be out for a few days now..

(little installation reminder debian-stretch-lite: user pi pass raspberry..for ssh enabling ->sudo raspi-config)
for the european „Sabre-Lover“ ;-), Audiophonics.fr has now also our ES9038Q2M „on sale“(50€)..(LINK)
seems its almost identical with our „green-boards“ here;
they have also +15V DC plug on it, so i guess its PCB 1.04 minimum/upwards..
(User „Zek“ (thx a lot!) here from the forum means:“..This board has an additional regulator for a 5V pin and an additional capacitor (in the middle).“(see comments).
by that there are also some pics with more technical details..(and as said, these „solder/unsolder“-thing)
by that, Audiophonics has also a toroidal transformer „Transformer Toric 30VA 2x15V“ (LINK) on sale for only 17,90€ which seems to be ideal for our ES9038Q2M-boards..
(and a wonderful „wiring/installation“-tutorial/pictures for these torodial-transformer->http://forum.audiophonics.fr/viewtopic.php?t=389)
check it out 😉
because everyone visiting this site is really „on“ new infos to the ES9038Q2M here are some pics and a description of the new „V1.06“-pcb-layout, i would call it the „Green V1.06„..($39$ Ebay/49$-41€ Aliexpress)
they assembled also a DC-plug (here +15V DC) to it.. (to use it you have to short/solder J6 (is left above the plug from this view))
but the default voltage stays at DC +15V 0 -15V and u can still connect it directly to the board->“* It is recommended to use dual DC+-15V power supply to play board best results„
the other difference i first saw that the 3pin-header (Volume) moved from „horizontal“ to „vertical“ (or vice versa)..The jumper row is now down to 5->
(maybe some other user can us tell the other differences in future)..
looks very nice 😉
today, after 60 !! days, my LCD1602+I2C-modul finally arrived..(2.00$ Aliexpress->LINK)
i have already a 2.6″ TFT-LCD display (320×240), but also want to check these 1602-LCDs (its „standard“ for the „real“-Arduino-User 😉 )
okay, there is not soo much to tell, except that i havent bring it to work in „full mode“ so far because (and thats why i write this article here too) it was the „hell again“ 😉 soldering the I2C-modul (in this case i took a 16pin pin-strip) on the LCD-PCB..
so if u can find a 1602-LCD with a I2C-modul already soldered on it, take it ;-)..
i extended my Bluetooth-IR-sketch now with a „blink“ from the whole display (“ lcd.backlight(); delay(250); lcd.noBacklight(); delay(250);“ 😉 everytime i make a command, type a „value“ via the Bluetooth-App; as confirmation..
Its blue and i first thought i print the source („CD,DVD,XMOS-USB etc..)“ on it; but there are no characters on it by now cause i guess i have to solder some pins again ;-(..
useful sketches i´ve found so far were:“identify the I2C-adress from the modul („i2c_adress.ino“) and a simple sketch to get data via the serial monitor and print it on the screen..(.inos and links here->http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=19 )
so far so good, many greets from here 😉
after i´ve got my „Arduino Mega 2560 R3“->on sale 11,99€ Amazon->LINK a few days ago, i just wanted to revive my „Project 1“ Cambridge Audio Azur A540 Remote via a „Bluepill“ (STM32F103C8T6) or an Arduino; original post here-> http://essabre-90xx-rpi.sfb2.com/2017/12/programming-subkurs-i-ir-receiver-raspberry-pi-project-1-cambridge-audio-azur-540a-remote/..
I´ve ordered an Arduino because this Bluepill/STM32-programming via the Arduino IDE is still very complicated at present imo, because there were nowhere really clear,simple instructions and libraries (pin assignments and so on)..(more maybe later)..
so i´ve decided to „fall back“ on this original Arduino-thing, hoped it would be easier at first for me..
long story short: (I´ve made a really long TuT over at the forum->http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=18)
because i didnt know how to send and receive IR-signals (simultaneously) and which pins i then i have to/use edit in the boarddefs.h (Arduino IRremote-library) i switched over to my HC-06 Bluetooth-Modul….
Full story (as said) here->http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=18
and now it works here absolute fantastic !!! 😉
came by chance over this !! :

and so, because i had great problems/was not possible to order from TaoBao direct, i got today a free 8$ coupon from yoybuy.com..checked it now for the first time and will then report here any info.. 😉
many thx to „Blackbear“ over at the Diyaudio.com-forum http://www.diyaudio.com/forums/digital-line-level/314935-es9038q2m-board-10.html
and because of min. 80% !! of the visitors here on the blog a searching for ES9038Q2M-related info, here are some results on his „research“:
In MoodeV4Beta on Dietpi he uses the „Audiophonics ES9028Q2M„-audio-settings..(for the ES9038Q2M)
„..Hello, in dietpi i had selected no driver = just left rpi-2835 (I left it without change after installation…), but in moode driver selection i choosed audiophonics 9028q2m, so it is strange that Moode takes control over dietpi driver (now I am thinking about it…) ? but it works, also tried to switch in dietpi config onto i-sabre-2km driver then restart and no sound so then i had to go into moode driver and to select audiophoincs 9028q2m, tehn reboot and it works again…strange..“
greets for now..
