Specification

• i2c MCP23008: 8-bit GPIO [Datasheet]
• J2 (GP0 ~  GP7): Output & GP0, GP1, GP2, GP3, GP, GP5, GP6, GP7 (8 Status LEDs output)
• R20, R21, R22 (A0, A1, A2) 23008 address select
• JP12 Disable Jumper
• i2c Real-Time-Clock: RTC-DS1307 [Datasheet]
• CR1220 battery socket
• i2c Temperature Sensor: 12-bit TMP102 [Datasheet]
• i2c EEPROM (24C32) [Datasheet]
• JP10 Disable Jumper
• i2c Digital to Analogue (D/A) converter: 12-bit MCP4725 [Datasheet]
• JP11 (AOUT, GND)
• JP1 Disable Jumper
• i2c Analogue to Digital (A/D) converter: 12-bit ADS1015 [Datasheet]
• J7 input: (AIN0, AIN1, AIN2, AIN3, GND, 3V3)
• JP12 Disable Jumper
• i2c output port
• J5 (5V, GND, SCL, SDL)

• FE1.1 USB 2.0 4-port hub
• J1 (JP3)
• USB Hub upper port signal: input from the Raspberry Pi
• Mini USB port 5V input for USB Hub
• J13
• You don't need to plug 5V in, the USB Hub already uses 5V from the Raspberry Pi (P1 Pin 2). If your USB device needs more power, then you can plug in 5V in this port.
• USB-to-TTL: FT232RL [Datasheet]
• J4 (USB input from PC: just connect it with the 5-pin Mini USB-B to USB-A cable). After that, you can have this serial console's function.
• USB-to-RS232: FT232RL and ZT3243 [Datasheet]
• ZT3243: RS232 Transceiver Driver
• If you use a PC/Mac/Raspberry Pi USB cable input, then you can have a DB9 full 9-pin RS232 output
