Giveaway Week 2023 – WCH CH583M-R0 development board and some RISC-V microcontrollers

Early this year, WCH sent me a few of their RISC-V MCU boards and chips to thank me for writing about their products. I gave one for review with some chips but it went to review heaven, or in other words, no review was ever written. I also sold a couple locally, and since I don’t think I’ll ever have time for a review, we are now giving away the remaining boards and chips here and on CNX Software Thailand.

Today’s giveaway is the WCH CH583M-R0-1v1 board, also known as CH583EVT or CH583M-EVT-R0, based on the CH583 RISC-V Bluetooth 5.3 LE microcontroller that exposes all I/Os from the chip, a few buttons, and USB ports, and also features an SWD/UART header for debugging.

You’ll find the documentation, code samples, an Android app and other resources to get started on GitHub.

I’ll also throw all the remaining chips I have left which should make this giveaway more interesting to people planning to make their own board(s). That includes five CH583 chips, three CH32V307 microcontrollers, and five CH32V003 “10 cent” RISC-V MCUs.

To enter the draw simply leave a comment with your country and whatever else you’d like to say (no links in the body of the comment). If the country is missing, I’ll consider the entry void. Other rules are as follows:

  • Only one entry per contest. I will filter out entries with the same IP and/or email address.
  • Contests are open for 48 hours starting at 10 am (Bangkok time) every day.
  • Comments will be closed after 48 hours. If comments are open, the contest is still going on.
  • Winners will be selected with random.org, and announced in the comments section of each giveaway.
  • I’ll contact the winner by email, and I’ll expect an answer within 24 hours, or I’ll pick another winner. Note that I may not be able to contact people who log in with Facebook, Twitter, or Google, so it’s better to use an email address to enter the draw.
  • Shipping
    • $11 for registered airmail small packet or ePacket for overseas shipping payable via PayPal within 48 hours once the contest (for a given product) is complete. If PayPal is not an option in your country, we can try to find another payment solution.
    • All prizes will be shipped at the same time once we get all the winners, so around November 15.
  • I’ll make sure we have 7 different winners, so if you have already won a device during this giveaway week, I’ll draw another person.

The board itself sells for around $8.5 shipped on Aliexpress, but that would be without the extra chips, and Thailand Post can’t quite compete with the ultra-cheap shipping options from China…
