Supporting up to 8-bit digital I/O and virtual COM mode, it streamlines sensor and memory device testing with script-based automation and LED safety indicators. Ideal for engineers and developers seeking reliable, multi-device connectivity and early-stage device operation analysis. ## Description This is an adapter to convert SPI/I2C bus used by sensors and memory devices to USB and connect to computers. You can control SPI/I2C devices from your computer, and it supports development by checking the operation of the device at the early stage and analyzing various sensor data, and implementing it with a microcomputer. Switching between SPI/I2C and Master Mo/Slave modes can be used with standard attached utility or library functions. Review: ７，８年前に購入したものを失くしてしまって、2回目の購入です。 I2C/SPIで電子部品やシステムの動作確認や評価するには最適な商品です。 WindowsのGUIを作る必要が無く、 ソースコードのコンパイル無用で、制御がテキストでできるのもハードル低いです。 ちょっと高価ですが、それだけの価値はあります。 ## Features - High Performance USB Connection Adapter for SPI/I2C - Slave Mode (2ch) to emulate devices - devices and this product power supply - supports up to 8-bit DIO; Enables automatic control via - script.
