pico-Platinchen is a pocket-sized, Arduino-compatible wearable board

This Arduino-sensor combination is perfect for your next wearable design.

Last year, Guido Burger had brought to our attention his impressive blueIOT. The open sensor platform was based on the ultra low-power combination of an ATmega328P MCU and a BLE module along with a single coin cell battery. Created in collaboration with the Fab-Lab Europe team, the board would on to be successfully implemented in a number of applications, ranging from DIY fitness trackers and smart socks to  magical Easter Egg hunts and hacked Nespresso machines — which you will actually be able to witness live at Maker Faire Bay Area.


Well, hot on the heels of its predecessor’s success, Burger has returned with the latest innovation from his crew: the pico-Platinchen. The uber mini, Arduino-compatible board was designed with wearable devices in mind and comes loaded with a high-precision, absolute orientation sensor from Bosch Sensortec. The BNO055 is joined by an ATmega328P, and like its older sibling, is powered by a CR2032 coin cell battery.

“The basis for your projects comes pre-integrated but you can still can expand it with more LEDs, sensors (e.g. I2C/SPI) and displays,” Burger explains. “Also, pico-Platinchen is a perfect basis for students and kids to start exploring the physical world: g-forces, magnetics, movements and much more!”


With a diameter of only 20mm, pico-Platinchen is ideal for projects that involve sewing, particularly hats. What’s more, the platform packs the punch of an Arduino Uno along with the flexibility of an entire 9-DOF sensor. And, to provide on-board notifications and color-fading, the Fab-Lab team decided to add some NeoPixels (WS2812 LEDs) that can drive up to 256 lights with the pico-Platinchen right out of the box.

“By the way, it comes with a lot horse power,” Burger adds. “The motion co-processor for 3D maths is an Atmel | SMART SAM D21. [The] gyro, accelerometer and magnetometer are [all] combined with high-precision and 100Hz update for an absolute orientation in 3D space.”


Using the Arduino IDE 1.0.7, Makers can build their own application with just a few lines of code in a matter of minutes. Aside from wearable projects, pico-Plantichen makes for a viable option in a variety of settings, whether that’s robotics, aviation or even in education (particularly physics). What’s more, the board can be coated for underwater projects.

Intrigued? The pico-Platichen is now available on Tindie for $32. Meanwhile, if you’re wondering what to make with the super small, wearable board, you can check out one of its recent projects on Hackster.io here.
