I’m beginner Arduino user (Arduino UNO) and I was looking to upgrade to a stronger hardware. Because my future projects need a lot of computing power. After compared all these other devices Firefly RK3288 (4GB RAM and 32GB storage version especially) seemed to be the right choice. But I don’t see much sources on the internet about it.
Can I use it like a Raspberry Pi or Arduino and do electronic development stuff like controlling servo motors, connecting sensors, lcd screens etc… Does it support C++ and Phyton?
Also do extension pins have analog in and digital out pins (supporting pwm output)? Is there 3.3v or 5v support?
In my opinion currently the board has better support for Android and development under Android than Linux. Given there is no TRM (technical reference manual) you need to be aware that any I/O interfacing that you require may involve you having to having to read the kernel driver code to work out what is happening or you to implement your own libraries.
