Have you always wanted an easier to use and more powerful Flipper Zero?

Are you tired of getting detained by the TSA because of your WiFi hat on your Flipper Zero? Then this is the solution for you. Its dimensions are exactly the same as the original iPhone 2G, meaning you can easily fit it in your pocket.

To make sure it lasts long and you don't have anxiety about your battery dying every minute, there's an onboard fuel gauge by ST and a 3000mAh battery. And of course, this isn't 2004, the touchscreen is capacitive, giving you the familiar smartphone like interface you're used to.

Hardware interfaces

LoRa for long range communication.

Sub-GHz for your favourite Flipper Zero shenanigans.

GPS for accurate positioning and tracking of your device.

Cellular connectivity (LTE-M) for getting firmware, updates, and any other cellular data without being restricted by WiFi.

Bluetooth for connecting other devices and other Bluetooth tasks.

WiFi for networking and your WiFi related shenanigans.

3.5mm audio jack, which real smartphones don't have nowadays.

MicroSD card slot for expansion.

USB-C for charging and uploading.

Accessibility

This is also designed from the ground up to be accessible. The 4 layer PCB is cheap, and it's also single sided, meaning you can get any reflow plate and solder it easily, no PCBA strictly needed. Single sided boards also make PCBA cheaper too.

Only have a soldering iron? No problem. The main radio interfaces, except GPS, are all hand solderable. Of course you won't have an IMU, fuel gauge, and 3.5mm audio, but because I chose easy to solder 0603 components, you'll have 90% of the functionality, with only a soldering iron, flux, steady hands, and some patience.

Note: a reflow plate is heavily recommended for reliability.

Pricing

$100 without PCBA, and $150 with PCBA. That not only undercuts the Flipper Zero, it also beats it at the same time.
