Shop by Form Factor
- UNO R3 (ATmega328P) – the classic 5V workhorse
- Mega 2560 – more flash, SRAM, and I/O pins
- Nano – breadboard-friendly; Mini-USB/Micro-USB/USB-C variants
- Pro Mini (3.3V/5V) – ultra-compact; external USB-TTL
- Pro Micro (ATmega32U4) – native USB (HID/keyboard)
- Leonardo (ATmega32U4) – native USB with extra I/O
- Due – 32-bit ARM; 3.3V logic (check shield compatibility)
Popular Shields & Modules
- Proto shields & I/O expanders for neat builds
- Relay shields & motor shields for control
- Ethernet (W5100/W5500), Wi-Fi, Bluetooth
- LCD 1602 shields, keypad shields, microSD modules
Essential Accessories
- USB cables: USB-A↔B (UNO/Mega), Mini-B / Micro-B (Nano/32U4), USB-C
- Power supplies & barrel adapters (5.5×2.1 mm)
- USB-to-TTL (FTDI/CP2102/CH340) for Pro Mini & bootloaders
- Breadboards & jumper wires, soldering tools
Compatibility Notes
- 5V vs 3.3V: UNO/Mega/Nano are typically 5V logic; Due/3.3V variants need level shifting for 5V shields.
- USB drivers: Some boards use CH340/CP2102/FT232. Install the correct driver if your PC can’t detect the board.
- IDE support: Works with Arduino IDE and PlatformIO; most product pages link libraries and examples.
- Powering: Prefer regulated 5V via USB for beginners; verify barrel-jack voltage limits per board.

FAQs – Arduino-Compatible Boards (Philippines)
Are these boards genuine Arduino?
We carry official Arduino and clearly labeled compatible boards. Check each product page for the exact variant and USB interface chip.
Which board should I start with?
Start with UNO R3 for tutorials and shields. Move to Mega 2560 if you need more memory/I/O, or Pro Micro (32U4) for native USB HID projects.
What cable do I need?
UNO/Mega use USB-B; many Nano/Pro Micro use Mini-B or Micro-B; some newer boards use USB-C. See “Essential Accessories” above for quick links.
Do you ship nationwide and support school/corporate orders?
Yes. We ship nationwide across the Philippines via trusted couriers and can prepare classroom kits and bulk quotations on request.
