Ampisu is a compact pocket-sized USB lab power supply with SCPI and web control (Crowdfunding)

The concept of a USB-C-based power supply is not new, and we have previously seen projects like XIAO Powerbread and Axiometa BrodBoost-C. As USB PD-based power adapters and power banks have become much cheaper, adjustable power supplies like the PocketPD and BenchVolt PD have come out. Both have their own limitation: the PocketPD has only a single output channel, thus hardly a lab power supply, and the BenchVolt PD is not quite compact enough to be considered pocket-friendly. This is where the Ampisu comes in. It's a compact, pocket-friendly, and isolated three-output lab power supply designed to fit in a pocket and include features of a typical full-sized power supply. Its desigened for low-power embedded work, field debugging, and automated test setups. Ampisu specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 125 MHz with 264KB SRAM Storage – Non-volatile memory for saving configurations Power Input 5V via USB Type-A or USB Type-C port

And finally - I overachieved earlier in the month, so I only have to do three a day now to hit my target for March - is something that was announced too late last week for me to cover: the addition of a new over-the-air update feature ("experimental," for now) to #RaspberryPi Connect:
