2. Pmod™ Interface
2.1 Overview
The RYZ012A1 Bluetooth Low Energy Pmod™ Expansion Board provides an interface using a 12-pin
Digilent Pmod™ compatible connector (CN1).
This provides access to:
•A high-speed UART interface (MSTR_CTS)
•An SPI interface (MSTR_SS)
•A mode reset pin (NRST)
•VDD and GND connections for module power
Pmod™ is registered to Digilent Inc. and its specification can be found at the link below:
