Kitronik Simply Servos Board for Raspberry Pi Pico

The compact Simply Servo board for Raspberry Pi Pico allows for up to 8 servos to be controlled simultaneously, making it ideal for advanced robotics projects with the RiPi Pico. The board should be used with a Pico that has soldered pin headers, the Pico can then slot straight into the board. A Pico with pin headers already attached can be obtained separately here. The board features standard 3-pin servo connectors which allow for servos to be plugged straight in without the need for adaptors or soldering.

As well as supporting 8 servos, the board also features 5 external connections to GPIO pins and a 3V and GND supply from the Pico. This IO breakout the 3 ADC pins and GP0 and GP1. This allows additional IO to be connected to the board and the state of these can then be read or controlled by the Pico.

Power is provided via a terminal block connector, the supply is then controlled by an on/off power switch to the board. There is a green power LED to indicate when the board is turned on. The board produces a regulated 3V supply that is fed into the 40-way connector to power the Pico, removing the need to power the Pico directly. The board's power connections are reverse polarity protected.

To support the board, Kitronik has developed a MicroPython module and sample code for controlling servos with the Pico. This code is available in the GitHub repo here.

Note: This board is not supplied with a Raspberry Pi Pico, one can be obtained separately here. This board is capable of continuous use at high currents. During such use, it may become hot.

Supply voltage goes straight to servos

These boards seem well built but be warned that the power input connector is wired straight to the servo connectors so if you actually connect 12V to the input, you better make sure your servos can handle that voltage.

It's nice that it regulates the input voltage down to 3V to power the Pico. I used this with a Pico2 and operating 8 servos simultaneously.

A comment unrelated to use design of this board is that servos can produce some pretty high current loads to the supply, specially at motion start. You may need to have a high current power supply or a large value low impedance capacitor across the input. I was using a 2.5A supply and see it regularly go into constant current mode (voltage drops) when the servos (4 micros, 2 standards, and 2 large) start moving.
