Powered by the RP2040, a chip that's beating the current chip shortage, Servo 2040 wears its purpose on its sleeve. Designed to control up to 18 servos, and work with up to six analog inputs, this is a serious board backed up by a well-crafted software library.
Servo 2040 is a densely packed board. It's slightly longer and almost double the width of a Raspberry Pi Pico. The 18 servo outputs feature three pins for each output. The pins are the Signal, Voltage and GND connection, and servos tend to have colour-coded connectors to show orientation. The headers are typical 2.54mm pitch and we can easily connect 18 servos, creating noodles of servo cables across your bench.
