In an era when the average application occupies many megabytes and requires dozens of libraries to run, it is still possible to fit the entire functionality of a device in 40kB of flash memory. Therefore, a single small ASR 6601 chip, in addition to LoRa radio communication, supports a display, buttons, joystick, UI, and more. Everything is based on FreeRTOS, with an AES-encrypted bootloader for easy and secure firmware updates.
It’s just a prototype, but it works quite well 🙂
Very nice, looks like it has only one joystick however two are required and some three position and two position switches.
