meArm Counterweight

thingiverse

I created a counterweight to increase the meArm's stability when sitting flat on a surface. The counterweight attaches to the back of the base plate and holds two 200g weights, similar to these: https://www.amazon.com/dp/B07GSTP68Q/ref=cm_sw_em_r_mt_dp_U_yrGLEb0RDP1JX. I also added space for a PBC to terminate servos and connect the meArm to a controller (RPI or PLC) via a 6-wire ribbon cable. The PBC can be found at https://www.amazon.com/dp/B0778G64QZ/ref=cm_sw_em_r_mt_dp_U_FAGLEbWETJ0CC, and the wiring diagram is included in the attached images. I designed a second PCB that mounts on top of the Adafruit servo hat for RPI to control up to four meArms.
