CH341A USB to I2C/IIC/SPI/UART/TTL/ISP Adapter EPP/MEM

Product Description

CH341A USB to I2C/IIC/SPI/UART/TTL/ISP Adapter EPP/MEM

Brief introduction

Single-chip integration of multiple functions, all hardware, to be completed

USB-> I2C Master a variety of adjustable rate, 20K 100K 400K 750K

USB-> SPI Master 2M rate, not adjustable

USB-> UART supports baud rate 50bps ~ 2Mbps baud rate can be configured unconventional

USB-> EPP / MEM Parallel

Simple, practical, high cost.
