Dongle pro
About the Dongle pro PCB
Dongle pro is an open source PCB design by fcjr, published on GitHub under the Apache-2.0 license. It is a 4-layer board measuring 26 × 98 mm, with 99 components from 31 distinct parts.
Other key parts include the RP2354A, FUSB302BMPX, HD3SS3220RNHR, GL3510-OSY52 and RT9013-33GB. By type, the board carries 52 capacitors, 22 resistors, 10 ICs, 8 diodes, 2 crystals and 2 connectors.
From the project
Reformat an Apple Silicon mac from any platform.
The USB 3.1 Gen 1 (5 Gbps) passthrough variant of the Dongle-Lite: same RP2354A + FUSB302B DFU-trigger platform, plus a GL3510 USB 3 hub in the data path and per-port SuperSpeed lane muxes. See ../README.md for the family overview (how the trigger works, Lite vs Pro, why the Pro doesn't restore faster) and ./PRD.md for the product spec (delta over ../dongle-lite/PRD.md).
