WiFi dongle pinout
SDIO interface is colored red:
- D0, D1, D2, D3
This is the interface for the 'NEW' WiFi module (based on Atheros AR6002) first included in DSi.
The proprietary and by now ancient DS-mode WiFi is colored yellow, pins are unknown.
I2C eeprom is colored blue:
SPI Flash is colored purple:
Monitors HOME button, WiFi switch, 3D slider, volume control slider. Controls LEDs, various power supplies.
Devices attached to I2C bus:
- UC (master?)
- Accelerometer (slave address 0x18)
- SoC (master? slave?)
