About the Esphome rgbcct led controller expansion PCB

Esphome rgbcct led controller expansion is an open source PCB design by mikelawrence, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 41.5 × 20.5 mm, with 19 components from 8 distinct parts.

Other key parts include the ADS1015IDGSR and REF35300QDBVR. By type, the board carries 6 connectors, 5 capacitors, 4 resistors and 2 ICs.

It belongs with the iot & wireless and sensors designs in this gallery.

From the project

ESPHome RGBCCT LED Controller is a PCB design that support a 5-Channel LED arrangement with Red, Green, Blue, Warm White and Cool White LEDs.

This is a simple expansion board used to add both thermistor measurement and i2c expansion, mainly for off-board temperature and humidity sensors like SHTxxx devices. Rev A has a JST ZR connector for the off-board i2c temperature/humidity sensor. This PCB is also designed in KiCad. Fabrication and is again tuned toward JCLPCB. 100% hand-soldered.

Rev A**: Has has fabricated, assembled and tested. No issues.
