Beam Offset Switch is an open source PCB design by nanographs: a 4-layer, 50 × 42 mm board with 29 components (12 distinct parts). It is built around the ADG5412_4X_SPST, RV1S9261A.

Just what you need to control the beam and get an image.

Glasgow makes getting bytes in and out of the FPGA over USB radically more accessible. We use that to make getting data into and out of your microscope radically more accessible.

- [X] Order and test rev 1 PCBs (Design not uploaded, required significant rework) - [X] Capture 16,384 x 16,384 images - [X] Live viewer fast enough to focus and stigmate with - [X] Raster pattern mode at 16,384 x 16,384 image resolution, with 8-bit grayscale dwell times - [X] Order and test V1.0 PCBs - [x] Refactor gateware to support 16-bit grayscale…
