MiKro-v1.0-Top

The MiKro – An Arduino UNO form factor based board using the ATmega 1284p micro controller

Hello everyone, some people have noticed on twitter that I was trying to compile the optiboot boot loader for the ATmega 1284p for the 5V/16MHz configuration. I finally succeeded and created the MiKro board which is described in a little more detail on it’s dedicated project page: http://www.mkroll.mobi/?page_id=1696 Although the the MiKro is work in progress […]

BLEBee and SODAQ: The perfect fit!

Hello everyone, this weekend I received a SODAQ beta board for some testing with the BLEBee and just grabbed some parts from my electronic boxes to create a “Plant Moisture Sensor”. The part list for this little project is: 1 SODAQ Moja Board 1 BLEBee (http://www.seeedstudio.com/depot/blebee-v100-p-1632.html) 1 Groove Moisture Sensor (http://www.seeedstudio.com/depot/grove-moisture-sensor-p-955.html) 1 Groove Cable (http://www.seeedstudio.com/depot/grove-universal-4-pin-20cm-unbuckled-cable-5-pcs-pack-p-749.html) […]

Firmware v1.1.0 available for the BLE-Shield v1.0.0

Hello everyone, I already published the new firmware v1.1.0 for the BLE-Shield v1.0.0 to my github repository which is available through this link: https://github.com/michaelkroll. In this firmware I omitted the internal 16 byte buffer so the shield now acts better as a serial bridge as before. I removed the control characteristics to query the content of […]

BGLib on the BLE-Shield v1.0.0

Hello everyone, I should have done this earlier, but good things need some time. As you might know, Jeff Rowberg @SectorFej as a BGLib Implementation created and published on github: https://github.com/jrowberg/bglib which runs on Arduino. You need a special firmware for the BLE112 module to be flashed which is available on his github repository as well. The BLE112 […]

A whole family of BLE devices. The BLEbee, the BLE-Shield v2.0.0 and the early version of the BLE-Duino 32u4

Hello everyone, this time I have a pile of news for you. Since the development of the BLE-Shield and the initial prototype of the BLEbee, I did some more research and prototyping on three new BLE enabled boards: BLE-Shield v2.0.0 (need another iteration before a private beta test) BLEbee v1.0.0 (almost ready for a private […]

KDuino

Preview of the K-Duino

Hello everyone, initially I was planning to use the ATmega2560, similar to the setup used on Sparkfun’s Mega Pro 3.3V https://www.sparkfun.com/products/10744 to create an Arduino Clone of my own. I played around with an ATmega644p some months ago before I created the BLE-Shield but I stopped working on it due to the lack of spare time invested […]
