Description

The Arduino® GIGA R1 WiFi brings the power of the STM32H7 to the Mega form factor, being the first Mega board to include onboard Wi-Fi® and Bluetooth® connectivity. The board provides 76 digital inputs/outputs (13 with PWM capability), 14 analog inputs and 2 analog outputs (DAC) all easily accessible via pin headers. The STM32 microprocessor with dual-core Arm® Cortex®-M7 and Arm® Cortex®-M4, together with onboard memory and audio jack enables you to perform machine learning and signal processing on the edge.
