Future is now (R)
After some research i know the protocols used now (rather public anyway), i just need to get my hands on a dev firmware – for usage on a stock ROM i dont need much besides external APKs enabled (or so i hope..)
Dev hardware is sadly hard to come by.
Pinout:
+3.3V: Power supply (Fused 3.3V DC Regulated)
V_BAT: Unfused Main battery voltage from the phone (3.7V to 4.4V)
ID: Identifies the connected Moto Mod
MOD_RESET: Reset line for the Moto Mod
USB_D+: USB data positive line
USB_D-: USB data negative line
I2C_SDA: I2C data line
I2C_SCL: I2C clock line
VBUS: USB power input
SPI_MOSI: SPI master output, slave input
SPI_MISO: SPI master input, slave output
SPI_CLK: SPI clock
SPI_CS: SPI chip select
AUX1: Auxiliary line for custom use
AUX2: Auxiliary line for custom use
The aux lines are not documented much, i need to see – for now i spectrum analyze my hasselblad camera and JBL speaker and see what i get out of that.
