Jumper Configuration

JP1 and JP2
- 1-2 : Internal regulator
- 2-3 : External Regulator
JP3
- Current measurement. Close it for normal usage.

Base board configuration

Followings are the configuration of the STM32G0B1RE.

Pin	Function
PA5	SPI1_SCK
PA6	LOAD
PA7	SPI1_MOSI
PB0	BLANK
PC5	RKEY1
PC4	RKEY2
PA10	RKEY3

Caution

Cut the 3.3V regulator of the Nucleo to measure the current of the STM32G0B1RE. Thus the total current can be measured by JP3.

Questions

How big is the Akashi-09 PCB?

It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Akashi-09 use?

50 parts, built around the MAX6921AUI. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Akashi-09 KiCad files?

From the suikan4github/Akashi-09 repository on GitHub, at the commit this page was made from: the board is Akashi-09.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Akashi-09 design in my own project?

Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
