This is a jtag probe with high-speed usb, a small touch display and a memory card. The memory card is useful for firmware images and data logging. This is under development. Changes may be made. ## Hardware - Artery (Yateli) AT32F405RCT7, 256 kbyte flash, 96 kbyte ram, 216MHz. - 280x240 LCD display with capacitive touch - ambient light sensor to set LCD brightness - 16 MByte QUAD SPI flash - SD card - CAN BUS - DS3231 real-time clock with battery back-up. - One high speed USB, 480 Mbit/s - One full speed USB, 12 MBit/s. - logic translators for logic levels below 3.3V - "Qwiic" I2C connector The box is 3D printed of transparent resin SLA 8001. The box is transparent because the ambient light sensor needs to be exposed to light. Because the AT32F405RCT7 is not in JLCPCB service, the processor has to be soldered by hand. ## Software As software I tentatively propose rt-thread, with [black magic probe](https://github.com/blackmagic-debug/blackmagic) and [free-dap](https://github.com/ataradov/free-dap)as an rt-thread package.
