About the RD40 PS V1 PCB

RD40 PS V1 is an open source PCB design by lhm0, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 120 × 120 mm, with 25 components from 15 distinct parts.

Other key parts include the Pin-Connector and LM317_TO-220. By type, the board carries 7 ICs, 6 capacitors, 3 resistors, 2 transistors, 2 diodes and 1 module.

It belongs with the iot & wireless and displays & leds designs in this gallery.

From the project

A DIY 40 LED rotating display with Arduino nano and ESP-01s microcontrollers

The Rotating Display device comprises two primary units: a power supply unit and a display board (figure 1). Both are circular in design, with a diameter of 120mm, similar to the dimensions of a standard Compact Disk. The display board is rotated by a CD motor. Energy is wirelessly transmitted from the power supply unit to the display board, eliminating the need for wired connections.
