BBSink

USB-PD sink with headers compatible with breadboard. Features a fixed 3.3V supply and one-click voltage selection without incorporating MCUs

LCD_Bias_Voltage_Generator

Except a 3.3V DVDD, LCD panels typically require 4 additional voltages: AVDD, VGH, VGL and VCOM. This board employs a simple circuit to generate these 4 voltages from a single 3.3V supply.

PCA9685_Breakout

Breakout board for PCA9685 I²C to 16-channel PWM controller.

BLDC_D28_Drv

Tiny driver stage for mounting on BLDC motors with 28/29mm diameters.

CH224Core

Tiny breakout board for CH224K USB-PD sink IC.

XPT2046_RTP

Breakout board for XPT2046 resistive touch screen controller.

yuyuyu_ant

Antenna for α-wave transmission( XD

50P_FPC_FFC_Breakout

Breakout board for FFC/FPC connectors with 50 positions and 0.5mm pitch.

40P_FPC_FFC_Breakout

Breakout board for FFC/FPC connectors with 40 positions and 0.5mm pitch.

24P_FPC_FFC_Breakout

Breakout board for FFC/FPC connectors with 24 positions and 0.5mm pitch.

14P_FPC_FFC_Breakout

Breakout board for FFC/FPC connectors with 14 positions and 0.5mm pitch.

9P_FPC_FFC_Breakout

Breakout board for FFC/FPC connectors with 14 positions and 0.5mm or 1mm pitch.
