The IoTbase Feather module has slots for installing one Adafruit Feather (or compatible) module and one mikroBUS module of the â€śSâ€ť or â€śMâ€ť format. These two slots organize a common bus. Using the Adafruit Feather slot allows you to design devices based on mikroBUS modules, various our modules, and Adafruit Feather compatible SoM such as:
- Huzzah32, M0 and M4 Express, nRF52840 Express, STM32F405 Express from Adafrui
- Xenon, Argon, and Boron from Particl
- MAX32620FTHR and MAX32630FTHR from Maxim Integrate
- Wio Lite W600 and Wio Lite MG126 from Seeed with all software and services from specified companies.
The MBL (P1) and MBR (P8) connectors are mikroBUS bus signals. Thus, it is easy to connect another module (or even several) with mikroBUS slots through these connectors, increasing the number of slots on the shared bus. In addition, almost all signals not used by mikroBUS from the installed Adafruit Feather are output to the P12 connector, making it possible to use almost all Adafruit Feather functions without changing the programs.
Third-party ESP-M3 modules can be installed in J4. Thus, a device based on IoTbase Feather can quickly provide a Wi-Fi connection. The ESP-M3 is UART controlled from the 2nd mikroBUS slot on the module. For stability, a DC-DC converter provides 3.3VDC power for the ESP-M3, independent of the power supply on the mikroBUS common bus.
The I2C interface is most often used in designing devices and instruments based on this module. The module has an I2C connector to connect external devices and sensors.
The module contains the LM75B chip – a temperature sensor connected via I2C. Temperature measurement accuracy: 2 C for the temperature range from -25 C to +100 C, 3 for the temperature range from -55 C to +125 C.
The module power supply is non-isolated, ranging from 9VDC to 36VDC. The module converts the input power to the output, 5VDC. The maximum current is 1A. There are two connectors for distributing 5VDC to other modules and a connector for transmitting VIN input voltage to other modules.
The IoTbase Feather module size is 65 x 56 mm. The format of the module corresponds to the popular format of the Raspberry Pi 3A+, which significantly simplifies its use with the Raspberry Pi.
The module comes fully assembled and ready to go. The module is part of our universal platform for IoT and IIOT, which was created to simplify users from design to implementation of projects and the start of production.
The main areas of application of the module:
- Industry and transport
- Ecology monitoring
- Data acquisition systems (DAS) and PLC
- Smart home
- Heating, Ventilation, & Air Conditioning (HVAC)
- Motor control
- Consumer electronics
