Shulou(Shulou.com)11/24 Report--

Thanks to CTOnews.com netizen OC_Formula for the clue delivery! CTOnews.com March 6, the new Arduino family, the new GIGA R1 WiFi development board based on dual-core Arm architecture MCU, the same shape as the existing Mega and Due, the size of only 101x53 mm, provides 76 GPIO pins, and supports wireless networks. This is Arduino's strongest development board to date, selling for $72.82 (CTOnews.com Note: currently about RMB503).

The development board uses a dual-core microcontroller (480 MHz Cortex-M7 core and 240 MHz Cortex-M4 core) STM32H747XI, equipped with 2MB flash memory + 1MB memory, can run two Arduino programs at the same time, such as micropython.

It supports up to 24V power supply (previous 12V) and increases the number of pins to 76 (including 12 analog ports, 13 PWM, 4 serial ports, 3 I2C, 2 SPI, 1 FDCAN, 1 SAI). Wi-Fi and low-power Bluetooth connections can be achieved by connecting an external antenna Murata 1DX module.

The board has a USB-An and a USB-C interface for power, programming, and HID functions (that is, simulating a mouse or keyboard when connected to a PC), connecting to a USB drive or other storage device, or an external mouse or keyboard; it also has input / output 3.5mm audio jacks, Jtag connectors (2x5 1.27mm), and 20pin Arducam camera connectors.
