CardputerZero pocket computer combines the brains of a Raspberry Pi Zero 2W with a tiny display, keyboard, and battery

The M5Stack CardputerZero is a tiny, portable computer that’s about the size of a small stack of business cards. But despite its compact size, it’s a full-fledged PC with a display, keyboard, and support for Linux-based software.

M5Stack has been selling similar devices under the Cardputer brand for a few years, but up until now they’ve featured ESP32 microprocessors and far too little memory […]

Cardputer Zero looks neat. Like a Flipper Zero that runs Linux, featuring the Raspberry Pi CM0 (i.e. a recently released stamp shaped Pi Zero module with DDR2 memory). *cough* it might make the Flipper One unnecessary. 🤷

I've got a Cardputer ADV, their previous gen ESP32 powered version. It's neat.

Sadly had to return the Cardputer Mesh.

After a few days of flashing, testing, and debugging I still couldn't transmit messages on MeshCore. Tested it in a low coverage and high coverage area - same results. Could receive flood messages but couldn't transmit.

Love the platform still, but for now I'm parking any projects using it. The Cardputer Zero might bring me back.

Looks like I'll have to DIY my first MeshCore node instead.

The #lora #rnode #cardputer #m5cardputer #ratcom code 1.9.2 included a fix https://github.com/ratspeak/ratcom/releases/tag/v1.9.2
and flashing from Chrome using the web flasher resulted in the #cardputer working as an #rnode directly with no problem accessing my existing lora #reticulum mesh.

New #meshtastic node of the #m5stack #cardputeradv variety. The bundled #Meshkit works right out of the box. I have a couple of #cardputer devices so I knew the real battle would be not futzing with the firmware on this one...so I got another non #lora ver to muck around on. If your in the #southdakota area , do a sweep and find waldo. (Face included for scale)

Has anyone made this #ratspeak #reticulum #microreticulum stand-alone work on a #cardputer #m5cardputer #esp32 https://github.com/ratspeak/ratcom ? I did not manage to get any lora radio announces from my extant lora rnode mesh to reach the cardputer nor for any cardputer announces to reach my rnode mesh, even with changes to codebase. (see fix in link below)

#cardputer adv. from #M5Stack has arrived today. Expanding the lab with its #esp32 microcontroller :)

The #cardputer is quite nice for #meshtastic and #meshcore .

The #cardputer looks like a really nice device:
dualcore ESP32 240MHz cpu, keyboard, wifi, 8MB flash, 240x135 display. speaker, mike, USB-C.
The 512kb RAM are to small to run #NetBSD .. but made me thinking if SD-card could be used instead of RAM. I mean, NetBSD runs on PDP which had slow core memory..

I saw the device researching for alternatives for a laptop, when doing FT8 / #HAMradio on a mountain summit. There is even code to run a radio transceiver!
