PROTOTYPE: Bus Pirate “Ultra” v1b

Today we finished stuffing the first Bus Pirate “Ultra” v1b board. This includes the updates we posted this week, and a few other improvements from v1a: 8 general purpose IO pins 0.8-5.0volt programmable power supply Voltage measurement on all 8 IO pins Pull-up resistors on all pins, fed from Vout/Vref pin Display connector USB C […]

PROTOTYPE: Bus Pirate/Logic Analyzer with Ice40 FPGA

Previous Bus Pirates relied on the hardware peripherals available in a microcontroller, which vary in features and have the occasional bug. With an FPGA we can implement practically any peripheral with all the fixes […]
