About the Baybasi panel PCB

Baybasi panel is an open source PCB design by riturajtiwari, published on GitHub under the MIT license. It is a 2-layer board measuring 100 × 95 mm, with 60 components from 19 distinct parts.

Other key parts include the SN74AHCT245N and AMS1117-3.3. By type, the board carries 27 resistors, 14 connectors, 9 capacitors, 4 modules, 3 ICs and 1 transistor.

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

From the project

WS2812B video wall: Raspberry Pi driver, upload utility, software DDP sink and ESP32-S3 controller firmware, with the KiCad board design

Software and firmware for a WS2812B video wall. The wall is 64 pixels wide and 192 pixels high. Each wall has 48 panels of 16 x 16 pixels.

There are two identical displays. The two displays do not share a cable, a ground or a clock. Each display is a complete and independent system.

The software runs today without hardware. A software DDP sink receives the pixel data and shows the result in a browser. You can test the driver and the upload utility before the boards arrive.
