Blip – An Upcoming IoT Development Board for Bluetooth Low Energy
Blip is an upcoming IoT development board, created by a Bangalore based company Electronut Labs is currently in the process of crowdfunding production at Crow Supply platform. Electronut Labs is an Embedded Systems company based in Bangalore which offers consulting services that help companies bring their ideas in hardware to market. They are also a very big supporters of Open Source and education, and their maker products cater to this segment.
Electronut Labs has previously launched various dev boards for education and open source like Papyr, an open hardware wireless display built with the energy efficiency of e-ink in mind. You can find other hobby and educational projects built by Electronut Labs here.
What is Blip Dev Board?
Blip is a development board for Bluetooth Low Energy (BLE) and 802.15.4 based wireless applications, based on the Nordic Semiconductor nRF52840 SoC. It has a Black Magic Probe compatible programmer and debugger built in, along with temperature/humidity sensor, ambient light intensity sensor, and a 3-axis accelerometer. It can be used to prototype very low power devices. It also has provision for an SD card slot, which makes it a complete and versatile development board.
Blip Hardware Specifications
Blips board packs following –
- Raytac MDBT50Q-1M module based on Nordic Semiconductor’s nRF52840
- LIS2DDH12 High-performance 3-axis “femto” accelerometer
- Optical Sensor LTR-329ALS-01
- Si7006-A20 I2C humidity and temperature sensor
- On board STM32F103CBT6 as Black magic probe debugger
- NFC Antenna
- MicroSD slot
- Power Supply: USB, JST connector for Li-ion/Li-po
- BQ24079 battery charging and power management IC
Blip runs at 5V USB supply or you can also use Lithium ion/polymer 3.7/4.2V battery to power it up on Vbat. If you using Vext pin you can supply 1.8V to 3.3V to Blip. The maximum battery charging current is 150mA and when powering with Vext, the debugger, charging IC, and LDO are bypassed for low current consumption.
Blip allows you to do many things with the on-board temperature, humidity, accelerometer and light sensors. It comes with default firmware. As soon as you plug blip, the firmware will start advertising the sensor values. You can also use the Electronut Labs mobile app to see the data coming from Blip. You can find sample firmware, datasheet, images etc. here.
Currently Blip is on pre-order at Crowd Supply and you can pre-order it now. Launch dates are not mentioned but if you have any question or doubts, you can email them at firstname.lastname@example.org.
Stay tuned for more updates on IoT development boards.
