See these boards in action in the repo IoT_Frameworks
This repository provides PCBs based on the STM8 which is the cheapest microcontroller on the market (Low and production volumes) with the cheapest debug and development environment.
PCB design using the STM8S103F bread board with the nRF24L01+ module. Provides connectors for I²C, UART and One wire.
This Board includes an STM8L151F3P6 (Low Power) the nRF24L01+, sensors modules : BMP280 (pressure, humidity, temperature), a MAX44009 (Ambient Light) and MRMS211H (Magnetic switches).
serial port commands issued in an ULN2804 general purpose up to 48V or 500mA per output
This board uses the 16 bit x7 channels PWM (from different timers) used to generate pulses for servomotors.
The IoT node is an STM8 based low cost development platform. It is an initiative for an open product = open hardware + open source project. find all the details in this link : http://www.homesmartmesh.com/mediawiki/index.php/IoT_Node
This board will be interfacing such peripherals :
- Radio transceiver module
- Weather sensors : temperature, humidity, air quality.
- RGB Leds
- Gyro / Accel
- Ambient light and user gesture
The wiki above contains links to SW and HW, but here's a direct link to the Firmware open source project: https://github.com/wassfila/STM8_IoT_HelloWorld The Firmware contains drivers (in development) for the above mentionned peripherals.
This IoT Node is part of a bigger project that extand the collaboration to a complete IoT environment. It includes interfaces to existing products and server applications for merging everything together. The "Home Smart Mesh" concept is described in the main wiki page http://www.homesmartmesh.com/mediawiki/index.php/Main_Page
The Board is grouping two modules :
- STM8 Dev Board based on the STM8S103F3
- nRF24L01+ module based on the reference design
- It also has a pullup resistor and 3 pins where to plug an DS18B20 temperature sensor
- It is possible to use these designs for commercial purpose
- It is possible to modify the designs
- It is not necessary to mention the original author of these designs
- It is possible to add your own name or company on the design
- It is not possible to prevent anyone else from having the rights mentionned above
