STM32L151 for Virginia Tech's camera experiment on AMSAT's FOX-1 satellite

Running ChibiOS 2.4.3 with some modifications for the processor and LQFP144 package. I forget exactly what I had to do to enable the peripherals I wanted, but they weren't quite fully implemented yet.

@ErikZalm
What is it? Industrial controller?

@MitchD
What the IC between camera and MCU? Is it RAM?

It's a dual port FIFO

It is a 3D printer controller.

I built an expansion board for the F4Discovery some time back.

Something from my side:

An SRAM and some LC-Filters are not populated yet. An SSD1963 based 5" touchscreen goes on top of that board (connector at the right edge).

What's that? an oscilloscope?

"Arbitrary Waveform Generator by Joel Bodenmann"... looks more like a signal generator!

Ah, I'd never heard of SiliconBlue FPGAs before, interesting! Very nice board, btw!

It is an arbitrary signal generator. Three channels, DC to 20MHz each, -12 to +12V with full range offset, three selectable filter banks (or bypass).
The hardware mainly consists of an STM32F102CB, an STM32F407ZGT and an ICE40HX FPGA. And it runs ChibiOS/RT & µGFX, of course

Thanks, my "biggest" board so far (four layer, 0.1mm traces and impedance matching and all the crap).
