About the Drv120 solenoid driver module
Drv120 solenoid driver module is an open source PCB design by MarkJB, published on GitHub under the MIT license. It is a 2-layer board measuring 36.5 × 15 mm, with 8 components from 7 distinct parts.
Other key parts include the drv120. By type, the board carries 2 connectors, 2 capacitors, 2 resistors, 1 IC and 1 diode.
From the project
Solenoid driver module that intelligently drives a solenoid via the TI DRV120 chip.
A small PCB module for efficiently driving a solenoid.
Originally designed for use with drawing machines for fast up/down pen control but applicable to any project that involves driving a DC solenoid (as a guide > ~30 ohms). A TI DRV120 chip drives the solenoid with a configurable PWM frequency and takes care of the initial fast energize required to get the solenoid moving then ramps down the current to a lower level to hold the solenoid in place. Peak & keep (hold) current and PWM frequency are configurable with resistors and caps (see schematic and data sheet).
