MikroElectronica Secure click board


The Secure click board from MikroElectronika carries the ATECC508A cryptographic coprocessor with secure hardware-based key storage. The click is designed to run on either a 3.3 V or a 5 V power supply. It communicates with the target microcontroller over the I2C interface.

MikroElectronica Weather click board


The Weather click board from MikroElectronika detects humidity, pressure, and temperature, specifically designed for low current consumption and long-term stability. The click is designed to work on a 3.3 V power supply. It communicates with the target microcontroller over the SPI or I2C interface.

MikroElectronica microSD click board


The microSD click board from MikroElectronika has a microSD card slot for microSD cards used as a mass storage media for portable devices. The microSD click is designed to run on a 3.3 V power supply. It communicates with the target microcontroller over SPI.

MikroElectronica USB UART click board


The USB UART click board from MikroElectronika uses an FT232RL USB-to-UART interface module and a USB mini-B connector. It communicates with a target board via a UART interface. The board is powered with a 5 V power supply, but is designed to use 3.3 V or 5 V I/O levels (selectable via SMD jumper).

MikroElectronica WiFi 7 (WINC1510) click board


The WiFi® 7 Click Board from MikroElectronika uses the ATWINC1510-MR210PB IEEE 802.11 b/g/n module, specifically optimized for low-power IoT applications. It is designed to run on a 3.3 V power supply. It communicates with the target microcontroller over SPI interface, with additional functionality provided by the following pins on the mikroBUS line: PWM, INT, RST.

Harmony example projects

Detailed documentation on select projects can be found on the development board support page. All example projects included in the MPLAB® Harmony software framework are documented in the Harmony Help file under "Volume I: Applications Help". To find all projects that use this specific board, search the Harmony Help file for pic32mx470_curiosity. This is the name of the board support package (BSP) assigned to this development board.

The following projects are included in Harmony version 2.05.01:

Project Name Location Description
Audio Demonstrations
sdcard_player.X <install-dir>/apps/audio/
The demonstration application creates an audio player that reads audio files (.WAV format only) from an SD card mounted on the click interface. The audio is played through the CODEC placed on the X32 header interface. It also provides the feature to switch to the next track on the media.
audio_tone.X <install-dir>/apps/audio/
In this demonstration application, depending on the configuration, the Codec Driver sets up the AK4384 DAC, AK4953 Codec, or AK4954 Codec. The demonstration sends out generated audio waveforms (sine tone and chirp) with parameters modifiable through on-board push buttons. Success is indicated by an audible output corresponding to displayed parameters.
cdc_com_port_dual.X <install-dir>/apps/usb/
This demonstration application creates a USB CDC Device that enumerates as two serial ports on the USB Host personal computer. This application demonstrates the ability of the MPLAB Harmony USB Device Stack to support multiple instances of the same Device class.
msd_basic.X <install-dir>/apps/usb/
This application demonstrates the use of the MSD Host Class Driver to write a file to a USB Flash drive. The application uses the USB Host_layer , MSD class driver and the MPLAB Harmony File System Framework to enumerate a USB Flash drive and to write a file to it.
msd_multiple_luns.X <install-dir>/apps/usb/
This application demonstrates the creation of a USB device with multiple logical units. The storage media, SD Card, acts as one logical unit, and the NVM acts as the second logical unit. Data transfer between a computer and the logical units (SD Card / NVM) takes place through USB MSD.
