Teensy packs serious performance into a tiny footprint. From the 600 MHz Teensy 4.x family to the proven 3.x line, these 3.3 V microcontroller boards deliver ultra-fast I/O, rich peripherals, and a polished Arduino workflow (via Teensyduino). Build responsive instruments, USB-MIDI controllers, advanced robots, and high-rate data loggers—right here in the Philippines.
600 MHz Power in Your Pocket — Why Makers Choose Teensy
-
Blazing speed: Teensy 4.x runs an Arm® Cortex®-M7 up to 600 MHz for real-time DSP, graphics, and control loops.
-
Pro-grade I/O: abundant timers, high-res ADC/DAC, I²S audio, multiple UART/I²C/SPI, and USB device/host* support.
-
Arduino-friendly: use the Arduino IDE with Teensyduino libraries, plus examples for audio, USB-MIDI/HID, and more.
-
Compact builds: breadboardable form factors that drop into handhelds, robots, kiosks, and stage gear.
-
Great ecosystem: shields (audio, Ethernet), displays, sensor packs, and plenty of community code.
Model quick picks
-
Teensy 4.1: maximum I/O and expansion; microSD slot, Ethernet (via external PHY), pads for PSRAM, and USB host* header—ideal for dashboards, audio rigs, and data logging.
-
Teensy 4.0: same 600 MHz core in a smaller board; perfect when space matters.
-
Teensy 3.x (3.2/3.5/3.6): proven 3.3 V platforms for legacy projects and libraries (availability varies).
What you can build
-
USB-MIDI & HID controllers: keyboards, drum pads, footswitches (native USB device on all Teensy models)
-
Audio & DSP: synths, samplers, and effects with the Teensy Audio Library; add the Audio Shield for codec I/O
-
Robotics & motion: multi-axis control with encoders, IMUs, ToF sensors, and high-resolution PWM
-
Data acquisition: high-rate ADC capture to microSD, stream over USB/Ethernet*

FAQs – Teensy Philippines
Do Teensy boards work with the Arduino IDE?
Yes. Install Teensyduino to add Teensy boards, cores, and examples to the Arduino IDE (including IDE 2).
Are Teensy pins 5 V-tolerant?
Teensy boards use
3.3 V logic; treat I/O as
not 5 V-tolerant. Use a
logic level converter when interfacing 5 V devices.
Which Teensy should I start with?
Teensy 4.0 for small builds with max CPU, Teensy 4.1 when you need more pins, microSD, Ethernet pads, or USB host.
Do you ship nationwide?
Yes—fast shipping across the Philippines via trusted couriers. We also support school/corporate orders and bulk quotations.
