Air105 Development Board

Air105 640kb RAM 4MB Flash 204Mhz devel­op­ment board MCU with 30W Cam­era com­pat­i­ble STM32 For ArduinoThe Air105 chip is pow­ered by a high-per­for­mance M4 core, with a max­i­mum fre­quen­cy of 204Mhz and built-in 640KBSRAM and 4MBflash. QFN88 pack­age, the size is only 10mm*10mm, a total of 56 pro­gram­ma­ble GPIO pins, chip built-in rich periph­er­al resources, not only pro­vides UART/GPIO/I2C/ADC/SPI and oth­er basic periph­er­als, but also pro­vides DAC/USB/DC-MI/HSPI/LCDI/KCU and oth­er advanced periph­er­als inter­face. Built-in lithi­um bat­tery charg­ing func­tion, sup­port 5V/3.3V pow­er sup­ply, at the same time with 5V to 3.3V LDO, great­ly sim­pli­fies the periph­er­al cir­cuit.The AIR 105 chip is pow­ered by a high-per­for­mance M4 core with a max­i­mum fre­quen­cy of 204 Mhz, 640 KBSRAM and 4 MBflash.
