About the BesteLampe! LED Moudule A PCB

BesteLampe! LED Moudule A is an open source PCB design by lenaschimmel, published on GitHub. It is a 2-layer board measuring 214.6 × 70.5 mm, with 140 components from 13 distinct parts.

Other key parts include the DS18B20U+. By type, the board carries 91 LEDs, 1 IC and 1 connector.

It belongs with the sensors designs in this gallery.

From the project

Die beste Lampe

This iteration of the design is a single layer PCB, to be manufacuted with an aluminum core. Adding though-holes into an aluminum PCB is very costly, so I made some effort to route all the LEDs series on the front layer.

See Module A2 for a variant with two layers and updated temperature sensor / memory chip.

I will soon compare the thermal properties of the Aluminum version (A) and the FR4 version (A2) of the board.
