Arduino GIGA R1 WiFi – Mega Power, Compact Form from Circuitrocks is ideal for DIY electronics builds.
Great for Arduino, ESP32, Raspberry Pi, and robotics or school projects here in the Philippines.
Arduino GIGA R1 WiFi brings workstation-class capability to the familiar Mega/Due footprint. Powered by a dual-core STM32H747 (M7 @ 480 MHz + M4 @ 240 MHz) with built-in Wi-Fi and Bluetooth®, it exposes 76 GPIO, high-resolution ADC/DAC, USB-C (HID) and USB-A Host, plus dedicated camera and display connectors—perfect for ambitious dashboards, audio/UI devices, robots, and research labs in the Philippines.
Mega Form Factor. Pro-Grade Power — Dual-Core 480 MHz + Wi-Fi/BLE
- Serious performance: run responsive UIs, fast control loops, or split tasks across M7/M4 cores.
- Modern connectivity: Wi-Fi 802.11 b/g/n and Bluetooth® (BLE) with a secure element for TLS.
- Rich I/O: 76 digital, 12 analog in, dual DAC, 12 PWM, 4×UART, 3×I²C, 2×SPI, CAN (via transceiver).
- Creator-friendly ports: USB-C for power/program/HID, USB-A Host for keyboards, storage, MIDI, etc.
- Audio & graphics ready: 3.5 mm I/O jack tied to DAC0/DAC1/A7, plus dedicated camera/display headers.
What you can build
- IoT dashboards & HMIs: Wi-Fi telemetry with TFT/OLED status screens and touch UIs.
- Audio & instruments: waveform synths, samplers, and audio players via the on-board DAC + 3.5 mm jack.
- Robotics & motion: multiple motor drivers, encoders, IMUs, and field buses (CAN/UART) running in parallel.
- USB gadgets: macro pads/MIDI/HID on USB-C; plug in keyboards or storage via USB-A Host.
- Vision & logging: Arducam sensor + local/USB storage + Wi-Fi upload for experiments and kiosks.

Pinout & power notes
- 3.3 V logic: use level shifters with 5 V shields/modules.
- Shields: UNO/Mega/Due shields that support 3.3 V are generally compatible; confirm library pin maps.
- USB-A Host: for HID/storage/MIDI; enable via the PA15 pin in examples.
- Antenna: u.FL external antenna is included in the box—attach for best Wi-Fi/BLE range.
- RTC & power control: VRTC pin for backup battery; OFF pin lets you shut down the board.
What’s in the box
- Arduino GIGA R1 WiFi board
- u.FL external antenna
FAQs – Arduino GIGA R1 WiFi (Philippines)
Will my existing shields work?
Yes—shields with the UNO/Mega/Due footprint that support 3.3 V logic typically work. Use the ICSP/SPI headers and check library settings for chip-select and pins.
Can I plug in USB devices?
Yes. Use the on-board USB-A Host for keyboards, mice, storage, and some MIDI/HID devices (see examples in the Arduino docs).
What power supply should I use?
VIN accepts 6–24 V. For benchtop use, USB-C is fine; for projects with motors/displays, use a quality PSU on VIN and keep cables short.
Is the antenna included?
Yes—an external u.FL antenna is included in the box; attach it for stable Wi-Fi/BLE performance.
Do you ship nationwide and support school/corporate orders?
Yes. We ship nationwide across the Philippines via trusted couriers and can prepare classroom bundles and bulk quotations on request.
Manila stock. Order before 16:00 PHT, ships today via J&T or LBC. Provincial: 1–3 working days.
Schools / class POs: we accept Purchase Orders for accredited schools and universities. contact us with your PO details.
Returns: 7-day inspection window for DOA units. Email proof of issue and we ship a replacement.
