Servo Tester
About the Servo Tester PCB
Servo Tester is an open source PCB design by Fabien-B, published on GitHub. It is a 2-layer board measuring 100 × 68 mm, with 36 components from 21 distinct parts.
Other key parts include the TSR_2-2450, MCP2551-I-SN, NUCLEO32-L432KC and PCA9554D. By type, the board carries 10 resistors, 5 switches, 5 capacitors, 4 ICs, 2 diodes and 1 connector.
It belongs with the robotics & motion designs in this gallery.
From the project
A device to quickly command servomoteurs and other stuff
The jumpers configuration on the NUCLEO L432KC needs to be changed: remove SB18, SB16 (for the I2C) and SB9 (to allow powering through 5V pin).
