rd
party add-on modules compatible with four most popular ecosystems using the following connectors:
1. Two Seeed Grove
®
system (I2C) connectors
2. SparkFun
®
Qwiic
®
connector
3. Two Digilent Pmod™ (SPI and UART) connectors
4. Arduino™ (Uno R3) connector
5. MikroElektronika™ mikroBUS connector

Connectors
5.3.1.1 Grove 1
A Seeed Grove I2C connector is provided at J27. The RA MCU acts as a two-wire serial master, and a
connected module acts as a two-wire serial slave.

5.3.1.2 Grove 2
A Seeed Grove I2C connector is provided at J28. The RA MCU acts as a two-wire serial master, and a
connected module acts as a two-wire serial slave. Alternatively, this port can be configured to support two
analog (ADC) inputs.
The pull-up resistors, R11 and R79, must be fitted when using I2C and removed when using as analog.
