Trellis core
About the Trellis core PCB
Trellis core is an open source PCB design by protolux-electronics, published on GitHub under the CERN-OHL-P-2.0 license. It is a 4-layer board measuring 50 × 50 mm, with 84 components from 25 distinct parts.
Other key parts include the TLV62569PDDCR, T113M4020DC0, USBLC6-2SC6, ZDSD04GLGEAG and SN74AHC1G08DCKR. By type, the board carries 44 capacitors, 25 resistors, 6 ICs, 2 crystals, 2 switches and 2 inductors.
From the project
A barebones KiCad project for Allwinner T113-based designs
This repo serves as a minimum hardware design for the Allwinner T113-S4 (part number sometimes referred to as T113M4020). This is pin-compatible with the T113-S3, but with 256MB of RAM in-package. Although generally software-agnostic, this repo is designed to be used with Nerves and nervessystemtrellis.
