It is one of those perfect devboard i need for my projects, especically my IoTs one, and i was pretty tired of conecting different modules together, wiring em and all, SO i thought that why cant i make a board than fulfills my need, and this may even come handy for many other hackers/dev too. This board comprises of inbuilt BMS, GSM, GPRS, GPS, RS485 communication, mic, speaker, sd slots etc with the main brain being esp32 s3 and A9G for gps/gprs/gsm.
Its pretty simple can just upload the code in firmawre/ through the usb connector or power it through the jst, and just upload code , interact with other modules as describe in schematic and BOOM ur powerful devboard workingggg. i will also try to make the complete datasheet very soon(probably after final exams ;D), some serial cmds to test the board:
help or ? - show command menu
status - show system info
reboot - restart system
sd.ls - list files
sd.cat - read file
sd.rm - delete file
gsm.at - send AT command
gsm.rssi - signal strength
gsm.sms - send SMS
gps.on - enable GPS
gps.off - disable GPS
gps.loc - get GPS location
485.tx - send data
pin.set <0|1> - set pin state
pin.get - read pin state
pwr.sleep - light sleep
pwr.vbat - read battery voltage
