This time it’s the Arduino Nano R4, a board based upon the same Renesas microcontroller used in the Arduino Uno R4 Mimima and WiFi boards. This gives the Nano R4 5-volt logic, like the Uno R4 boards. It also has a Qwiic connector for I2C. The Nano R4 has some interesting features, including a DAC, real-time clock, and an operational amplifier. We’ll see how to get these working (currently, there is a bug in the OPAMP library; I will show you how to repair it).
