the board uses less than 10uA at idle with the radio turned off and 5mA while updating the e-ink display.
@th is there an open source system for it? Maybe without cloud? 🥺
@th Are they battery powered? I thought they just kept the same display with no power.
@FritzAdalis the price tags have two CR2450 batteries in parallel and wakeup occasionally to receive new images over the 2.5GHz radio.
@th I see pyqtgraph
@th
at first I thought you meant that the price (tag) on the eink display was nice, but perhaps that's also the case
@th I have a few tags from a well-known Dutch supermarket. Part # HS_EL5102_1M_62_04. Wonder if this can be controlled by same software on your gh repo. Edit: it's also a Hanshow brand.
@artelse that model appears to be a totally different CPU with BLE and an LED. Somenoe else has made progress on reverse engineering it https://twitter.com/atc1441/status/1456590284763058185
@th yes, thx, that's the one I have. Aaron explains the flashing of new firmware with gh repo link here on the tubes: https://youtu.be/ANHz7EgWx7k
@th I have been eying these PCBite probe kits as they seem very handy. What is your experience? Did you also get the scope probes or can normal probes be used with them?

@artelse they work fairly well, although they are also quite expensive. I also have the 50 MHz scope probe versions since the regular jumper wire ones get fuzzy after a few MHz.
@th Yes, I see at Eleshop.nl it'll set you back eu200 or so. They also don't have the 50MHz version probes, only 100 and 200MHz. Hmm...ponder ;)
