## Overview

The Latock System REX-USB61mk2 is a high-grade USB adapter that converts SPI/I2C bus signals to USB, enabling professional-grade emulation and control of up to two SPI/I2C slave devices simultaneously. 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。
