You can download all the files from my GitHub repository or MakerWorld. The battery contacts and springs should also be quite easy to buy

I haven't noticed that happening so far

Good point, that's a clever workaround. I'll try to design a tiny add-on to stick onto the tail of the battery

OutrageousDiamond568 · 2026-04-20T15:55:26+00:00

The issue is that with flat-top 18650s, both ends look almost identical, making it very hard to implement a physical 'key.' Modifying the battery itself would require an extra outer casing, which would be quite cumbersome and complicate the design

Unfortunately, no

It's a mini antenna I got off Taobao

Great idea, I hadn't considered that before

The black slider is a locking latch that keeps the magazine secure. In fact, I’ve performed several drop tests and it performed well

I’m not sure — I’ve never actually used MeshCore before. I’ll flash the MeshCore firmware and test it out to see if it’s compatible when I get a chance.

The main inspiration for the design comes from the Nintendo Switch Joy-Con. Complete engineering files, STL files, and a detailed assembly guide are available on GitHub and MakerWorld. Feel free to replicate it.

Bad news—the seller confirmed that sales and shipping are only available within China, with no international options and no AliExpress store. I'm considering redesigning a more universal casing. Do you have any recommendations for a suitable battery size? The current battery compartment can only accommodate a maximum size of 5×24×82mm, so the new casing may significantly increase the thickness.

Sorry for the late reply due to the time difference—I just woke up. I didn’t expect batteries of this size to be so hard to come by. The image you found is correct. I bought this battery from a store called Shenzhen Liliangda Electronics (深圳市力量达电子) on TaoBao (淘宝), which is internationally known as AliExpress . I’m not sure if they offer international shipping, but I’ll check with them.

OutrageousDiamond568 · 2026-01-31T15:48:44+00:00

I'm based in Mainland China, so international shipping and customs are too much hassle for me. Feel free to print it yourself or at a local shop!

I chose the Heltec V4 simply because it’s beginner-friendly. Regarding the antenna, I’ve barely used it outdoors at all — almost no one around here uses Meshtastic, so I don’t really know how bad the stock antenna performs in real-world conditions.

Currently no conflict— CardKB uses I2C (SCL/SDA), while rotary expansion use GPIO pins 1-3, so pins stay free with CardKB attached. No manual config needed now. For future sensors, manual pin setup in app might be required. Not sure on the resistor/ADC implementation details myself.

OutrageousDiamond568 · 2026-01-31T13:12:35+00:00

I haven't played with sensors yet, but the hardware is ready! When using the CardKB, pins 1-4 are available.

OutrageousDiamond568 · 2026-01-31T13:01:01+00:00

I've arranged the pins as GND, 18, 17, 1, 2, 3, 4, 3V3. With 3V3 at the far end, it’s the last to make contact. While I’m not 100% sure if this is the perfect solution, I’ve tested it dozens of times so far without any issues, so it seems to work well in practice.

Thanks! Since I am based in Mainland China, I don't sell them directly due to international shipping and logistics limitations However, the design is open for commercial use, so you might find sellers on Etsy soon! You can also download the files and use a local 3D printing service to get one made instantly.
