Xassette-Asterisk

Evaluation board for AllWinner's RISC-V 64 SoC F133/D1s

Highlights

• Breaks out all IOs, involving analog peripherals, in a compact 56*56mm 2-layer board
• Comes with standard interfaces including USB, micro SD, LCD, Line-in and headphone
• Optimized components arrangement for soldering on heating tables

About the Chip

D1s/F133: RISC-V 64 single core @1.008G with in package 64MB DDR2

Schematic

The schematic in KiCAD format is available under hw.

Notes

• Leave all BOOT selection resistors unconnected if only one BOOT media is present
• Choose load capacitors according to specs of crystals
• When board is to be powered by 3.3V, connect to the power via the 3.3V pin of the pinheader, and D4 should be soldered. Note USB host will not work properly in this condition due to the absence of 5V power.
