v1.1.0
- Split microphone audio / bias (#132)
- Added more GND vias near power vias
- Minor adjustments to schematic labels
- DNF components now not shown on iBOM
- J901 is a header not a socket
- External LED drive is 5V 20mA
- Moved passives clear away from expansion slot legs
- Updated STEP model
- Added new top-down view to README.
- Set BMC part as being STM32F030K6T6 (F031 is unavailable)
- Specify THS7316 as default video buffer (TPF133A and DIO2663 should also work)
- Stitching vias for ground planes, and wider traces between vias and pads
NB: We wrote some assembly instructions after v1.1 was tagged, which you can find here: https://github.com/Neotron-Compute/Neotron-Pico/blob/develop/ASSEMBLY.md
Known Issues
- RGB DAC output voltage is wrong
- causes dim video picture (400mV max instead of 700mV max)
- replace R510 R610 and R710 with 585 ohm, or turn the brightness up on your monitor
