Posted on August 7, 2014 by R-B Leave a comment

Microchip introduces new PIC32 Bluetooth® Starter Kit to ease the development of Bluetooth enabled products such as thermostats, wireless gaming controllers, barcode scanners and diagnostic tools.

Microchip Technology Inc., a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced the new PIC32 Bluetooth® Starter Kit. The full-featured kit boasts a PIC32 microcontroller (MCU), HCI-based Bluetooth radio, Cree high-output multi-color LED, 3 standard single-color LEDs, an analog 3-axis accelerometer, analog temperature sensor and 5 push buttons for user-defined inputs. Additionally, a PICkit™ On Board (PKOB) which eliminates the need for an external debugger/programmer, USB connectivity and GPIOs for rapid development of Bluetooth Serial Port Profile (SPP), USB and general-purpose applications. The starter kit also features a plug-in interface for an audio CODEC daughter card which is set to release at a later stage to support Bluetooth audio.

Jianan Li, a ECE and CS student at Duke University, has designed this 5V LiPo Booster based on TI’s TPS61230 IC. It is breadboard-friendly and it can be directly plugged into the power rails of breadboards of multiple sizes without blocking the vertical 5-pin strips. Jianan has posted the Eagle design files and BOM on Github.
