A PCB for the Raspberry Pi to create a flexible sensor evaluation board.
Provides the following features:
- HAT identification EEPROM
- 12V DC input
- Battery backed RTC
- Temperature/Humidity Sensor
- 8 differential ADC
- 23 GPIO
- 8 I2C connectors
- 4 SPI connectors
- Debug LEDs (can be disabled)
- 4 port USB hub
- RS232 connection / TTL Serial
- 2 TTL Serial ports
- RS485 connection
- Pycom Socket
- SD card
- Control of Raspberry Pi Power
- 2 TTL Serial ports
- I2C connection
- SPI port
- 8 GPIO
Most of the passives and some of the semi conductors are available in the Seeed studio OPL, additional components then need to be sourced and hand soldred.
