The microcontroller ATmega88 is the bases of this device. The ATmega88 communicates with Ublox NEO6MV2 and accelerometer. This is SMS alerter, which is sending sms or more precisely ATmega88 is sending AT commands to mobile phone (Nokia 3210) and it is sending sms with actually GPS coordinates. You can download complete code and you can watch video.

If you have our development board with SIM908 or something else, you have to know AT commands for GSM/GPRS/GPS module. Repetition again. You have to connect UART from SIM908 module to your microcontroller (Tx module – Rx microcontroller, Rx -…
I had to create development board with SIM908 – GPS&GSM&GPRS module for diploma thesis. The board is designed as top side. It’s easier than top and bottom sides. On the board are pin headers which are connected to the SIM908…
The cnx-software website shared interesting news about clone of ATMega328P called LGT8F328P microcontroller by LogicGreen. The manufacturer promises 99% compatibility with popular ATMEga328P microcontroller by Atmel/Microchip. What is the 1% uncompatibility nobody knows. The manufacturer gives better parameters of microcontroller.…
A fresh update from Heltec – the IoT device manufacturer – has improved the popular Heltec LoRa 32 from version 3.1 to v4. The chip is based on the ESP32-S3 Wi-Fi and Bluetooth chip, with LoRa connectivity provided by the…
The development boards are very popular. I decided to share this list. These boards are interesting, popular and cheap (to 30? – by farnell.com). If you click on the picture, you will be redirected in eshop, where you can buy…
BigClown, popular IoT platform, offers a lot of TAGs (board with sensor) and modules, but I still had missed versatile board for connection of cheap sensors from ebay and aliexpress – e.g. BMP280, Si7021 or SHT31. Notice: HARDWARIO s.r.o. doesn’t…
