The IoTbase Nano module has slots for installing one Arduino Nano (or compatible) module and one mikroBUS module of the “S” or “M” format. These two slots organize a common bus. Using the Arduino Nano slot allows you to design devices based on mikroBUS modules, various our modules, and Arduino Nano compatible SoM such as Arduino Nano, Arduino Every, Arduino Nano 33, and Nucleo-32 family (NUCLEO-F031K6, NUCLEO-F042K6, NUCLEO-F303K8, NUCLEO-G031K8, NUCLEO-G431KB, NUCLEO-L011K4, NUCLEO-L031K6, NUCLEO-L412KB, NUCLEO-L432KC, NUCLEO-8S207K8) from STMicroelectronics with all software and services from specified companies.
The MBL (labeled P1) and MBR (labeled P8) connectors are all mikroBUS bus signals. Thus, through these connectors it is easy to connect another module (or even several) with mikroBUS slots, increasing the number of slots on the common bus. Almost all signals not used by mikroBUS from the installed Arduino Nano are output to the P12 connector, which makes it possible to use almost all Arduino Nano functions without changing the programs.
Third-party ESP-M3 modules can be installed in J4. Thus, a device based on IoTbase Nano can be easily provided with a Wi-Fi connection. The ESP-M3 is UART controlled from the 2nd mikroBUS slot on the module. For stability, there is a DC-DC converter that 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 the design of devices and instruments based on this module. For this, the module has an I2C connector through which you can 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 С for the temperature range from -55 C to +125 C.
The module power supply is non-isolated, in the range 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 Nano module size is 65 x 56 mm. The format of the module corresponds to the popular format of the Raspberry Pi 3A+, which greatly 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 the step from design to implementation of projects and the start of production.
The main areas of application of the module:
- Consumer electronics
- Air condition monitoring
- Distributed Data Acquisition Systems
- Smart home
- Smart sensors
- Motor control
