  Sandisk serial number check. And now with hardware hobbyists and technological tinkerers moving away from the most popular USB to serial adapter, some other chip has to fill the void. The cheapest USB to serial chip on the market appears to be the CH340G, available for 20-40 cents apiece from the usual retailers. There is, however, almost no English documentation, and the datasheet for the CH340 family doesn’t include this chip. He got his mitts on a few of these chips and managed to figure out the pinout and a few reference schematics.

  He even made an Eagle part for you. Isn’t that nice? The CH340 series of chips do exactly what you would expect them to do: a full-speed USB device that emulates a standard serial interface, with speeds from 50bps to 2Mpbs. The chip supports 5V and 3.3V, and all the weird modem lines are supported. This chip even has an IrDA mode, because wireless communication in the 90s was exactly as rad as you remember.

  Usbserial: USB Serial Driver core when I check /dev there is a 1-1 device ( /dev/1-1) When I plug in a USB stick it detects the media but I can not mount the media.

  With [Ian]’s help, we now have a cheap source of USB to serial chips. If you need the datasheet,. The driver is a bit more difficult to find, but what you’re looking for is the CH341 family of chips. That can be found with a little bit of Google fu. • • • • Posted in Tagged,,,,,, Post navigation. It might be worth mentioning that Windows 10 Technical Preview (build 9860) loads Microsoft’s CDC serial driver (USBSER.SYS) automatically. Assuming they don’t revert or regress before release, Windows 10 will finally solve USB serial driver install for all class-compliant USB serial devices.

  

  As Windows users migrate to version 10, we’ll finally have a situation where USB serial devices work as well on Windows as they have for many years on Linux and Macintosh. Microsoft also fixed the long-standing surprise removal bug in the driver. It’s not just the price of the chip, they need other parts like resistors, capacitors, crystal oscillators, etc. You need to incorporate the prices of these parts in your comparison.

  And then you need to factor in availability, a cheap chip is irrelevant if you can’t get them (or the supporting parts!) in the quantities and timeline you need for your project. You also need to factor in board space, in three dimensions. Big capacitors can be really cheap but they are problematic if you have size constraints. The datasheet referenced is only for the CH340T and CH340R, both 20-pin parts and NOT used on Arduino clones. The only datasheet I’ve seen that has the 16-pin CH340G is mostly in Chinese. However it is enough to be able to use the CH340G is a new design (your own Arduino clone maybe?).

  I am using it in a project where I put the equivalent of a clone Arduino Nano on my board. Here’s a ASCII version of the pin-out since I haven’t figured out how to post a picture yet: ———————— 1 GND VCC 16 2 TXD RS232 15 3 RXD RTS# 14 4 V3 DTR# 13 5 UD+ DCD# 12 6 UD- RI# 11 7 XI DSR# 10 8 XO CTS# 9 ———————– The rest of the Chinese datasheet is the same as the English version. You can match up pins in the example schematics well enough to use it in a design. I created an Eagle library for this part (and only this part), but I’m not sure how to share on HAD yet. The Cypress UART chip also supports SPI and I2C. And the USB Battery Charging spec.
