kinda amazed you can get a microcontroller SOC board w/ case, battery and a screen for about 50 bucks shipped.

And if you are willing to compromise on the lack of case and a smaller screen you can get them for as low as 6 bucks shipped. Look for the ttgo esp32 with usbc and integrated lipo charging circuit, can highly recommend them!

Also recommended here.

Check these out. ESP32 (wifi+bluetooth), lora radios, GPS, oled screen, and battery holder - ~$25US:

I have four of them, all work exactly as described.

And what tda is talking about for ~$8US: https://www.aliexpress.com/item/32824839148.html

Or no screen, but with an SD card slot for %5US: https://www.aliexpress.com/item/32846099054.html

I bet that last one would run Hash Monster just fine - if you need a screen for feedback - they're under $3: https://www.aliexpress.com/item/32922106384.html

The LILYGO® TTGO T-SIM7000G also makes a great autonomous wigle throwie.

Ooooh. A nano SIM and an LTE antenna. But no quickly googlable info about what cellular capabilities it has. I'd _assume_ it does 3G/4G/LTE? Have you ever used that? (We don't have any GSM/2G left where I am, so a lot of the inexpensive cellular project boards dpn't work here any more...)

I ordered one several weeks ago from their tindie store, I'm still waiting on delivery. Spec sheet says global-band LTE. I've read that the ~free (they might be $10?) google fi sims cards 'just work'.

Apologies for the implied existing success.

It is based on SIM7000G, which is LTE CAT-M1(eMTC) and NB-IoT. So "4G".

Oooh, thanks!

(Goes back to still open tab to order a couple... Don't now what for yet, but you know shrugs:. Hmmm, I've got Meshtastic running on some other TTGO boards, I wonder how much work it'd be to bridge two LoRa mesh networks together over SMS or the internet?)
