This PCB provides a maximum of eight ERM/LRA drivers and two transistors to control binary actuators. All haptic actuators can be controlled through an Adafruit Feather HUZZAH32 microcontroller.
All SMDs are on one-side of the PCB only to reduce costs for the assembly service.
This board was designed using KiCad 6.0.
The part list is divided into two sections, the first one contains the parts if you decide to only solder the through-hole components yourself. The second BOM contains the SMD components.
