BRIGHTDOT WEARABLE DEVELOPMENT BOARD

This BrightDot is an ATmega32U4 based, Arduino compatible development board that you can use as a wearable or e-textile. Be creative and use the multicoloured RGB LEDs to brighten up your wardrobe, decorations, backpack or even make Christmas ornaments!

The alligator friendly pads/holes enable you to quickly prototype your creation. The pads were also made bigger to ease the use of conductive wire and they are gold plated to ensure durability. The integrated single cell LiPo charger makes the LED badge more versatile, even though it has an existing open system.

The 24 BrightDot LEDs (WS2812) enable you to display bright and colourful animations with just a single pin!

This module comes preloaded with a watch program and an onboard hardware real time clock. The real time clock enables you to keep the time, even when the ATMega32u4 is powered off (but the power supply must stay connected). With the onboard single colour LED and button, you can quickly debug and test programs without any wires. To top things off, a dedicated ON/OFF switch is included to keep the power consumption as low as possible when youre not using the device.

ESP32 WEARABLE DEVELOPMENT BOARD

Get ready to meet the most versatile wearable and ESP32 based development board of the moment! Its 100% Arduino compatible and its easy and invisible to wear thanks to its uniquely thin PCB with 8 x sewable pads. Plus, it wont sting you because the PCB design has no sharp edges. Also, 4 of the pads are capacitive touch-enabled.

As for the versatility, this little development board of 56 x 50 x 7.5 mm packs a lot of features such as a hall effect sensor, a temperature sensor and an ultra-low power analog pre-amplifier. But the neatest on-board feature is undoubtedly the ability to connect the board to WiFi and Bluetooth. Getting any ideas? Heres one: connect the board with our BirghtDot wearable LEDs collection and make them react to text or social messages, magnets, sounds, time, temperature and more!

You can easily connect this wearable with a battery thanks to the JST connector and you dont have to worry about high power consumption because the board also features a deep sleep modus to keep its consumption to a minimum when you dont need it. To top things off, this thin board is at least 10 times faster than an Arduino Uno because of its super high 240 MHz clock.

Go take a look at the BrightDot wearable LED boards and get creative!

Při kontinuálním měření se velmi zkracuje životnost sondy, neboť zde probíhá elektrolytická reakce.
Pro optimální životnost sondy i baterie naprogramujte periodické měření s okamžitým vyhodnocením výsledku.
