Raspberry Pi Zero 2 W / ESP32-S2 (ESP12K) / Skysong ES9038Q2M
as i unfortunately “burnt” my green SMPCB 1.07 + the power-board from the BDP9500 (schniff ;-( , had not fixed the +12V-0V–12V cables correctly, only “so half-way” 😉 , moved the sabre-board a little bit and voila: a nice grey cloud lifted up here above the power-board 😉 ) (but i ordered a new one (ES9038Q2M), see at the bottom), i´ve meanwhile recognized the arrival from the new Raspberry Pi Zero 2..
has 4 cores @ 1GHZ (instead of 1 core before) (same amount (512MB) ram), some newer Bluetooth (4.2) BLE and cost about 19$->https://buyzero.de/products/raspberry-pi-zero-2-w (u can read a lot about it in the web->https://www.raspberrypi.com/products/raspberry-pi-zero-2-w/ )
(i still thought to use it as “control” for the LCD1602-display, the relais for the inputs (coax+tos) + “webcontrolled” (see other projects before), but i guess the “boot-times” for the Pi Zero 2 (also for Micro-Python btw.) are too long, so i guess i stick back with the ESP32 but this time i think i use “micro-python” because u can use the same “sketches”/python-scripts on the both platforms (its easier + more interesting for me at present (super easy to flash and work with micro-python on the ESP32 btw.))..
and so i found a newer revision of the ESP32; the ESP32-S2 (ESP-12K)..it has only one but newer core, a little less ram, without bluetooth (was either way too resources-hungry) + has a better usb-support etc..cost only about 5€; is here->https://de.aliexpress.com/item/1005001489650877.html
so, and as i either way “burnt” an “old” SMPCB 1.07, i thought this time i buy a
“Skysong” ES9038Q2M with display and poti; 45€ from here->https://de.aliexpress.com/item/32979155509.html
(i wrote about this particular ES9038Q2M-board already here-> http://essabre-90xx-rpi.sfb2.com/?p=2211)
and i think/thought that as they made such a phenomenal XMOS-USB-bridge (“..best xmos-implementation..”)->http://essabre-90xx-rpi.sfb2.com/?p=1040
it could be really an upgrade to the SMPCB 1.07(will report more then about it)..by that these ES9038Q2M-board is DSD512-compatible (didn´t read it somewhere else) + special japanese condensators + u can also use some Apple TV remote (3€) to select the input-channel (I2S,coax,tos) + volume adjustment + select digital filter..
by that, a new “Moodeaudio” is out (7.6)->https://moodeaudio.org/
nothing else new from here, guess i want to buy a new (spare-part) Philips BDP-9500 power-board (for the dual 12V) and will maybe post a python-script for the web-controlled/IR-receiver/LCD1602 for the “ES9038Q2M-Box” in future..
but greets from here and have a nice pre-christmas-time ! 😉
