Controller T41 rev0.3
About the Controller T41 rev0.3 PCB
Controller T41 rev0.3 is an open source NXP PCB design by brianamos1, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 102.9 × 69.9 mm, with 51 components from 15 distinct parts.
Its main chip is the Teensy4.1, from the NXP family. Other key parts include the AMS1117-5.0 and 74HCT245. By type, the board carries 33 resistors, 6 ICs, 5 connectors, 3 capacitors, 2 diodes and 1 fuse.
From the project
A board for driving 32 strings of pixels from a Teensy 4.1. Similar to the OctoWS2811, but with 32 outputs.
This board interfaces with a Teensy 4.1, and is designed to use the OctoWS2811 library to drive up to 32 strings of LEDS.
Version 0.2 is designed to use the Amphenol RJHSE508004-ND, which is a four port RJ45 jack. Version 0.2a uses the Adam Tech MTJG-4-88GX1-FSB, which is a less expensive and more readily available alternative.
The 2x3 pin that connects the board to the Teensy 4.1's ethernet pins is available on digikey and mouser, however is easier to source from PJRC when purchasing the Teensy 4.1. If you want the teensy to be removable, PJRC is the recommended source for that connector.…
