#WCH #RISC-V-MCUs im Test: Was können 10-Cent- #Mikrocontroller aus #China?

Auf den ersten Blick ist das Angebot von #WCH ziemlich erschlagend: Zur Auswahl stehen Dutzende Varianten mit unterschiedlichster Peripherie – diese reicht bis zu Ethernet- und USB-2.0-Schnittstellen. Bei vielen handelt es sich allerdings um reine #Protokollwandler, die für uns uninteressant sind. Wir haben uns für die #Modelle #CH32V003, #CH32V203 und #CH570 entschieden.

New PCBs from #jlcpcb . First time doing hot plate soldering, only had to fix one solder bridge! so much easier than using an iron on these 0.5mm pin pitch parts.

Of course it doesn't work 😄 I got the connector pins backwards... Luckily they make a reversed connector so these boards don't go into trash, just have to wait for new parts!

Over the weekend I worked on the Sharp LCD version of the Pocket CO2 project and things are starting to come together. This one uses the CH32V203 which has 64K FLASH and 20K SRAM. The nice thing about having a 128x128 LCD and an IMU is that the display orientation can follow the 4 possible device orientations.

This morning's project - turn this frustrating solderless breadboard failure into a reliable soldered version on 2-sided tinned protoboard.
