Contents
Features
- (19) GPIOs, GVS pins
- GVS pins
- (3) UARTs, GVTxRx pins
- GVTxRx pins
- (1) I2C bus, GVSdaSck
- GVSdaSck
- (8) Channels of 3.3V to 5V level translators
- Use female to female jumpers to route the GPIO lines to the translator channels
- 5V side has GVS pins
- (7) 1.8V analog GVS connections with analog voltage/ground
- Buffer opamps on the analog inputs
- 5V pins are all ESD protected pins with 15 kV of protection
- Selectable 5V source (SYS_5V or VDD_5V)
LEDs for 3.3V and 5V power
- Cape configuration EEPROM with write enable jumper
- Beaglebone Black form factor
