Abstract:
In recent years, advancements in microscope design have allowed faster, higher resolution imaging of all types of biological samples. Custom microscope designs have rapidly seen adoption, enabled by a rapid growth in open source software. In this report, we present a custom, open source, hardware design which provides two 16-bit resolution high-speed analog outputs as well as breakouts for GPIO connections to the inexpensive and well-supported microcontroller (the $5 Raspberry Pi Pico 2). We provide firmware for interfacing the device with software and demonstrate the device performance. This device provides a working platform for development of custom microscope hardware.
