About the XassetteAsterisk PCB
XassetteAsterisk is an open source PCB design by SdtElectronics, published on GitHub under the CERN-OHL-W-2.0 license. It is a 2-layer board measuring 56 × 56 mm, with 137 components from 56 distinct parts.
Other key parts include the F133, W25Q32JVSS, SY8089AAAC, SY7201ABC and XC6206PxxxMR. By type, the board carries 59 capacitors, 35 resistors, 13 connectors, 13 diodes, 7 ICs and 4 inductors.
It belongs with the dev boards & breakouts, audio and iot & wireless designs in this gallery.
From the project
Evaluation board for AllWinner's RISC-V 64 SoC F133/D1s
Pins for LCD and DVP camera can also be used as IOs. See schematic below for detailed pin assignment.
The schematic in KiCAD format is available under hw. BOM in csv format is at docs/BOM.csv, and kitspace provides an online BOM. Do note that many components are optional (required by some specific peripherals)!
NOTE: hw-v0.1 board can NOT boot fw-v0.2 firmware. Use fw-v0.1 instead.
