MotorDriver-Controller_v4の機能+αと電源回路を合体させた統合型電源基板
1. DriveUnit Bseriesを使用したいチャネルのカードエッジコネクタに差し込む． 1. モータードライバを差し込んだエッジコネクタと同じチャネルにモータを接続し，必要に応じて同じチャネルのコネクタにロータリーエンコーダを接続する． 1. 非常停止スイッチを刺したコネクタの下にあるトグルスイッチをONに，それ以外のトグルスイッチをOFFにする． 1. XT90とUSB Type-Cからそれぞれ電源を供給し，非常停止スイッチをONにすると稼働する． > Note > USB Type-C用電源を省略する方法はDescriptionsを参照
JP6で信号用の電源をUSB給電or外部給電に切り替えることができます． 外部電源としては，SPOWのピンに接続された電源かリポバッテリーか選ぶことができます． リポバッテリーの場合は「GND」と「SPOW」のピンヘッダを短絡してください． その際にE5VのLEDが点灯していることを確認してください．

Azusa: common questions
What microcontroller does the Azusa use?
The Azusa is built around the LQFP64, from the STM32 family.
How big is the Azusa PCB?
The Azusa measures 105 × 137 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Azusa?
298 components, from 218 distinct parts. The full bill of materials is listed on this page.
Where can I download the Azusa design files?
From the issaimaru/PowerSupply_v1 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Azusa design in my own project?
Yes, under the terms of its Apache-2.0 license, which issaimaru chose for the repository.
Can I test firmware for the Azusa without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
