Building OpenIPC FVP gears
It’s amazing that someone spend their time to run wfb-ng directly on CCTV camera board running hacked linux OS. The RX part is also amazing because it utilize $20 Nvr board 🙂 If you want find out more you need to follow the guide https://github.com/OpenIPC/wiki/blob/master/en/fpv.md The thing i done it’s only design of 3d printed […]
LoRa chip running whole device
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. […]

E78-868LN22S (ASR6501) module SWD programming
I have spent a lot of time to find out how to upload/debug your firmware to CDEBYTE E78-868LN22S modules, which are based on ASR6501 chip, which included PSOC 4 MCU (compatible with CY8C4147AZI-S445) and Lora SX1262 radio. The MCU is Cortex M0 running at 48Mhz, 16kB RAM and 128KB flash memory (as far as i […]
