This is an 8.14-inch 4-color SES electronic shelf label e-ink screen driver board with dual ICs (IC suspected to be JD79686AB) and dual ribbon cables. Theoretically, it can also be used with 6-color boards of the same size. It comes with an adapter FPC, with pins identical to those in the Waveshare 7.3G, where the CS pin of the IC is located on pin 34.

35 Closed-loop stepper motor driver board && vise control board
This project used CNC sheet metal and some mechanical parts to fabricate an electric welding vise. The CNC components were prototyped at JLCPCB's 1 Yuan CNC prototyping event. The drive section uses a closed-loop stepper drive, and the motor drive board is suitable for a 35 stepper motor.
Project Introduction:
This project utilizes CNC sheet metal and some mechanical parts to construct an electric welding vise. The CNC components were prototyped at JLCPCB's 1 Yuan CNC prototyping event. The drive system uses a closed-loop stepper drive, and the motor drive board is compatible with a 35 stepper motor. It can be used in other projects. The plan includes the following functions: closed- loop button setting for
vise position, automatic adjustment of clamping current (to be implemented), long-term automatic sleep mode (to be implemented), external control input (to be implemented), and manual version video demonstration: bilibili.
