TD1204 / Sigfox & GPS

Telecom Design provides 4 different chips to support SigFox communications. This post details the differences of each of them in term of functionnalities

All are modules are based on a EFM32 / Cortex M3 micro-controler with 128KB flash, 16KB RAM, ultra low power including a Silicon Labs transceiver. The chip is a EFM32G210F128

Telecom Device TD1205 – Sigfox – Test

The TD1205 device is more than the usual Telecom Design Sigfox embedded circuit as TD1204 and TD1208, they are a all in one chip providing GPS antenna and RF antenna. Ready to use, to be clear you just need to plug a battery to use it.

In my point of view, for many applications not requiring more than 2 GPIOs, this product is really easy and chip way to design a SigFox product. As it costs around 55$ and you just have to add box & battery id sounds like the most affordable for small quantities. But …

This post is detailing what is specific to this chip ; read more following the link

SigFox arduino Raspberry PI hacking board

I assume you know a little bit who I am and what I’m doing, I’m not the one to by > 100€ to buy a one shot development board kit to test & hack a device like the Telecom Design chip. So basically I built my own with the objective to work with multiple configuration.

My “cahier des charges” was to make a board able to be installed as a dauther board on a raspberry PI,  able to support an arduino, able to run autonomously and being able to own a TD1204 as a TD1208.

It was a huge work to route it and I must recognize that it do not have all the GPIO connected as I expected but it exists, it works and it help me to build my first SigFox prototypes with success.

So, now, I propose to distribute this board to those of you looking for a such swiss knife.
