Hardware This chapter describes the hardware features of the PIC32 Bluetooth Starter Kit 2.1 HARDWARE FEATURES The following key features of the starter kit are presented in the order provided in 1.2 “PIC32 Bluetooth Starter Kit Functionality and Features”. Refer to Figure 1-1 and Figure 1-2 for their locations on the development board. 2.1.1 Bluetooth Module The FLC-BTM805 is a dual-mode Bluetooth HCI module that allows original equipment manufacturers to add Bluetooth wireless capability to their products. The module supports BT2.1 and later with an HCI interface, which makes it simple to design into fully certified embedded Bluetooth solutions. The module supports Bluetooth Enhanced Data Rate (EDR) and delivers up to a 3 Mbps data rate. In addition, the module supports Class 1 transmission and multiple device connection. 2.1.2 Processor Support The development board in the starter kit is designed with a permanently mounted (i.e., soldered) PIC32MX270F256D microcontroller. Support for this microcontroller is available using the Microchip MPLAB® X IDE v2.10 and later, and with the MPLAB XC32 C/C++ Compiler v1.32 or later. 2.1.3 Powering the Starter Kit Use one of the following methods to provide power to the starter kit: • Connect USB bus power to the USB debug connector, J7 • Apply VBUS (+5V) power to the micro-B USB connector • Connect an external application board with a regulated DC power supply that provides +5V to the J8 header (not populated) 2.1.4 USB Connectivity 2.1.4.1 HOST MODE Connect the device to the Type-A connector, J1, which is located on the top of the starter kit development board. 2.1.4.2 DEVICE MODE Connect the starter kit to the Host using a cable to port J2, which is located on the bottom of the starter kit development board. 2.1.4.3 DEBUGGING MODE The starter kit includes a PIC24FJ256GB106 USB microcontroller that provides debugger connectivity over USB. The PIC24FJ256GB106 is hard-wired to the PIC32 device to provide protocol translation through the I/O pins of the PIC24FJ256GB106 to the ICSP™ pins of the PIC32 device. Connect the starter kit to port J7, which is located on the top side of the starter kit development board.  2014 Microchip Technology Inc. DS70005190B-page 17 PIC32 Bluetooth® Starter Kit User’s Guide 2.1.5 Switches Switches, SW1-SW6, are available on the development board of the starter kit. SW6 is connected to the reset pin (RB5) of the board. When Idle, the switches are pulled high (+3.3V), and they are grounded when pressed. 2.1.6 Other Features The starter kit is integrated with a temperature sensor, the Cree high output multi-color LED with PWM, a 3D- accelerometer, and an authentication connector.
