The value of the Flipper isn't so much the hardware, it's the documentation and ecosystem. Unfortunately, any other project will have to do a lot of work to compete, but it's a worthwhile attempt.
Too bad that flipper didn't upgrade the hardware to include bluetooth and wi-fi at minimum. Makes it really limited. Also, the price for purchasing a device went really high compared to the initial price of 100 euros per unit.
The WiFi board unfortunately lacks the polish that the rest of the unit has. It’s like minimally attaching a bare raspberry pi to your Flipper in the most awkward way possible. They really should have built this in, particularly considering plenty of ESP-32s come with Bluetooth and WiFi for very, very cheap.
