- 2 x grove I2C connector to connect other I2C devices
- 2 onboard nice WS2812 RGB LED
- Footprint for Atmel ATSHA204 (I2C version due to lack of I/O)
- Footprint for Microchip 64 bits Unique ID 24AA02E64 (on LORA version)
- Created a version with NRF24L01 connector instead of a grove I2C (end of this page)
- SMA oo UFL Antenna connector


This page has been updated to reflect the GPIO changes and the PCB also, it's now V1.3.

New Version 1.3 boards
======================
New boards version V1.3 these boards have minor improvments
* SMA/UFL Antenna connector has been size reduced
* Antenna trace and RF Module surrounded with via for better RF isolation
* Increased "Isolate" ground planes to avoid shorts between connectors and ground (may happen sometimes after soldering)
* I2C OLED connector is now "lock" version, you can just plug to test it will fit without connector
* No more LED solder pad to choose VIN/3V3, added 1N4148 diode from 5V for the 1st LED to decrease VCC to 4.4V, always works
* LORA version, added Microchip 64 bits Unique ID footprint 24AA02E64
* LORA version, done a diode logic OR for DIO0/DIO1/DIO2 for current LIMC implementation

You can order the PCB of this board at [OSHPARK][3] (V1.2) or the new V1.3 version at [PCBs.io][13].
PCBs.io give me some reward when you order my designed boards from their site. This is pretty good, because I can use these rewards to create and design new boards and order boards for a discounted price, so if you don't care about PCB manufacturer please use PCBs.io.
