ScopeFun hardware sources on GitLab have been updated with the following changes:
- added serial resistors on digital GPIOs (R_56R) to improve frequency response
- replaced resistors on digital GPIOs: R_1k_0.5W 0805 -> R_470R_0.33W 0603 (reduces output impedance)
- replaced capacitors C138 C139 (C_47uF) with C_10uF (reduces current draw during startup to avoid possible FX3 reset)
- added optional GND screw terminal (GND_P2)
- updated component descriptions
PCB boards ordered and delivered through crowdfunding campaign on Crowd Supply are manufactured according to latest hardware version (with above changes already included).
