About the Grow light-LEDS PCB
Grow light-LEDS is an open source PCB design by GeoffreyKassis, published on GitHub. It is a 2-layer board measuring 125 × 70 mm, with 22 components from 3 distinct parts.
By type, the board carries 20 diodes and 2 connectors.
From the project
USB-C PD grow light in two assemblies: an FR-4 controller (MAINBOARD/) and a one-layer aluminum LED panel (LEDBOARD/), joined by an 8-wire 2×4 IDC harness. Schematic connectivity and the as-drawn BOM come from KiCad (MAINBOARD/production/, LEDBOARD/production/). This file records

USB-C is the only power inlet. An HUSB238 PD sink negotiates the contract over I2C. An STM8S003F3 requests 9 V or 12 V (never 20 V) and PWM-dims four TPS61165 boost channels from PC6. Each channel drives one isolated LED string: four 4000 K whites plus one 660 nm red in…

Grow light-LEDS: common questions
How big is the Grow light-LEDS PCB?
The Grow light-LEDS measures 125 × 70 mm, has 2 copper layers and is 1.645 mm thick.
How many components are on the Grow light-LEDS?
22 components, from 3 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Grow light-LEDS design files?
From the GeoffreyKassis/led_grow_light repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Grow light-LEDS design in my own project?
The repository has no license, so all rights stay with GeoffreyKassis. Use it as a reference, and ask the author before reusing the design.
