About the Prototype-2 PCB

Prototype-2 is an open source PCB design by mylife-home, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 87 × 68 mm, with 32 components from 15 distinct parts.

Other key parts include the 4N35 and H11AA1. By type, the board carries 15 resistors, 5 ICs, 4 connectors, 3 transistors, 3 diodes and 1 capacitor.

From the project

MyLife Home devices

- 20 IO au moins - mettre un Switch ou jumper pour relier les phases et neutres de 2 entrées sorties voisines (pour pouvoir relier ensemble ceux qui viennent du même disjoncteur)

- IO / disjoncteurs: - R1: 7 + 3 extension + escalier - RDC: 5 + porche - Dehors: terrasse (vers spa)

- Rpi pico: 2 modules with 10 I/O each with io port0 = Zc + power supply - Rpi pico + esp : jumper pour alim séparée => permet live debug usb + reboot ? - Borniers "détachables" ? - Noter sur le silkscreen a quoi correspondent les borniers/pin headers/jumpers - Grouper les IO 4 par 4 (1 phase et 1 neutre pour 4 IO)…
