As quickly as I noticed this product itemizing, I needed to instantly go lookup extra details about this chip. This CH347 Improvement Board has, because the title suggests, the CH347 chip in addition to a USB-C interface and a DIP swap. The options blew me away once I first learn them: USB to UART, I2C, SPI, JTAG or simply GPIO! We’ve all bought drawers stuffed with USB to serial UART boards for programming Arduinos and different gadgets that use serial, however this chip takes issues a step additional and provides a bunch of different serial protocols. It’s just like the Swiss Military knife of USB chips!
It brings to thoughts the venerable Bus Pirate, an incredible board by Harmful Prototypes which lets you join to only about any serial protocol on the market, in addition to a number of different options. Whereas this chip has a few of those self same options, the interface is sort of totally different. This chip remains to be so new that it has barely began showing in Western markets but, so that is your likelihood to be forward of the curve! That in fact additionally means there may be little or no software program but out there for interfacing with this chip.
The corporate that makes the CH347, referred to as WCH, does have some documentation on their web site, but it surely hasn’t but been translated into English. There’s a datasheet obtain for many who can learn Mandarin, however I think a lot of the experimentation can be wanting on the demonstration code offered right here. The chip can run in a couple of totally different modes, together with HID (Human Interface System) which means it could actually act like a keyboard or mouse and ship knowledge that approach. It additionally helps CDC which permits it to ship knowledge in a wide range of methods, together with showing as a COM port. The demonstration code could be very Home windows-centric, however as soon as the protocol is discovered, I think it gained’t be lengthy in any respect till we see software program for this chip on all platforms. As soon as that occurs, anticipate to see this chip in all places!
