EPS is an open source STM32 PCB design by rgw3d: a 4-layer, 85 × 85 mm board with 629 components (71 distinct parts). It is built around the STM32L496ZGTX, MR25H10, TPL5010, TPS270 and more. Filed under science & space.

Hardware design files for my $1000 CubeSat.

Hardware design files for my $1000 cubesat.

Schematics & Layouts are done using KiCad V5.1+

My progress so far, what I'm calling the ½ Cubesat. The avionics board is stacked on the eps board

See my fork of the OpenLST repo for more information!
