How to: Build you own Bluetooth Low Energy IBeacon for 10 $ DIY
IBeacons become more and more popular but most companys charge about 30$ for them. Thats way to much, so lets to it ourselves.
But first… the Shoppinglist:
HM-10 (http://imall.iteadstudio.com/im130614001.html) 6,50$
Battery Holder for Coincells (http://imall.iteadstudio.com/im120803016.html) 0,20$
Protoboard (http://imall.iteadstudio.com/im121207002.html) 0,60$
Steel Pins (http://imall.iteadstudio.com/im120706003.html) 1,50$
CR2025 CoinCell 1,00$
First we should have a look in the datasheet (HM10 are made by http://www.jnhuamao.cn/) and search for this graphic:
Important for us are actually only UART_TX, UART_RX, GND and 3.3V. If you want you can also use pin23 and pin24 to have leds on you beacon. But using the leds will cost energy.
Next we take the steel pins and bend them in a way that they match the indentations on the HM-10 board. Than we can start soldering.
I also soldered some pins on the right side of the HM-10 this give more stability and it won’t break so fast.
We also need Pins to connect them to a serial interface and flash new firmware or configure the module.
