A serendipitous Taobao discovery means that ZZH* might ship with a cheap and cheerful plastic enclosure. Sent off some test gerbers, going to be a tight squeeze as the PCB had to get a bit shorter... * https://electrolama.com/projects/zig-a-zig-ah/ …pic.twitter.com/LjbSI75WFZ

Getting there! Not particularly happy about the chopped up SWD header (better than not having one!) and need to find a tiny low-profile pushbutton that doesn't suck. Also new USB-UART chip and smaller TVS and LDO.pic.twitter.com/A3nHx1JPiC
