The BOKRA Base A+ 5W module is designed to install mikroBUS modules and provides a device based on this module with non-isolated 5VDC power, up to 1A.

The module has two slots for installing mikroBUS modules of the “S” or “M” format. These two slots organize a common bus.

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. Third-party ESP-M3 modules can be installed in J4. Thus, a device based on BOKRA Base A+ 5W can be easily provided with 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 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 module comes fully assembled and ready to go. The module is part of the BOKRA 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 BOKRA Base A+ 5W module size 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 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)
• Power on / off
• Consumer electronics
• Gaming Applications
