New low-end CH32V microcontrollers from WCH

[HwAoRrDk]

Actually, WCH sells them on AliExpress. 50pcs of CH32V002 for €10.13

Huh. I'm surprised, that's the first time I've seen any for sale anywhere. And I've been looking every few months since my original post. Curiously they don't appear on an AliExpress search for "ch32v002" - at least, not on the first couple of pages that I could be bothered to look through. No '004 or '006 either on the WCH store.

I find the WCH official store to be very odd - frequently they'll, for some reason, have zero product listings, i.e. the store is empty. I don't know what the deal is with that.

The search engine on AE is notoriously bad. I often use Goo..le instead, adding "Aliexpress" to my search.

You're right that the '004 and '006 don't seem to be available, but the '002 is listed in the store, not just the direct link.

Perhaps it won't be long for the others.

I didn't notice this earlier, but the one review on the listing says that the customer received unmarked chips.

Parts are not T&R, but in small jewel cases. They are also completely unmarked. The only indications on their tops is the mold mark by pin 1--so at least it's got that. I'm going to have to mark them all manually.

I don't quite understand what the seller reply is trying to say:

Hello friends, we are new to this chip, you buy the chip has not been engraved on the silkscreen. At that time, we have told you, if you mind, you can cancel the order. Now our chips are available to have a stamp!

Are they implying you would need to specifically ask them for marked chips, otherwise you'll be getting unmarked?

Does the 002 really come in an exposed pad SO8 as shown in the image?

I'm writing to the store, I'm curious what price they'll offer me for the ch32v004 ssop20

There's no clear plan for mass production now, we need to wait a bit. Thank you for your understanding and your support of WCH, I will still let you know when 004 hits the shelves at a later date.

Doubt it. According to the one review there is on the AE page,

Color:50pcs CH32V002F4P6
Parts are not t&r, but in small jewel cases. They are also completely unmarked. The only indications on their tops is the mold mark by pin 1--so at least it's got that. I'm going to have to mark them all manually.

So the pictures do not reflect reality.

There's rumours of cnlohr playing with CH32V006 engineering samples...

I've seen the CH32V002 and CH32V006 for sale on AE, but they aren't on LCSC yet. Tossed together the symbol for the QFN32 in KiCAD so I'm hoping I'll have some of the 006 models arriving at my door at some point.

I'm excited for the new CH32V007 chips, looks like they are going to integrate the half-bridge drivers for motor control usage.

Just will be kinda cool to say its the double oh seven when someone asks what uC a design is using.
