"The ThinkNode M2 by Elecrow is a compact Meshtastic handheld that nails the form factor but stumbles on power efficiency. At $43.90 ready-to-use or $21.90 bare board, it's one of the smallest handhelds available, small enough to work as a keychain (though a bit bulky). With a 1.3" OLED screen, buzzer, and excellent build quality, it checks almost all the boxes. But there's a catch: it uses the power-hungry ESP32-S3, which limits battery life to around a day despite its tiny 1000mAh battery."
"The build quality is really good way better than expected for the price. The injection-molded ABS case feels solid and well-finished, not cheap or flimsy at all. This isn't a 3D-printed enclosure; it's a properly manufactured product that feels premium in hand. The form factor is where the M2 truly shines. It's the smallest ready-to-use Meshtastic handheld we've reviewed even smaller than the T1000-E, though noticeably thicker."
The ThinkNode M2 by Elecrow is an ultra-compact Meshtastic handheld available ready-to-use for $43.90 or as a bare board for $21.90. The unit features a 1.3" OLED, buzzer, and injection-molded ABS case that delivers a premium, pocketable Tamagotchi-style form factor small enough to function as a bulky keychain. The device achieves surprisingly strong radio range for its size and excellent build quality. The major drawback is the choice of an ESP32-S3 MCU, which results in high power consumption and limits the 1000mAh battery to roughly one day of use. Setup is straightforward; low-battery behavior includes a loud non-default beep.
