Microchip Technology recently launched next-generation Bluetooth Low Energy (LE) solutions intended for Internet of Things (IoT) and Bluetooth Beacon applications: the IS1870 Bluetooth LE RF module, the IS1871 Bluetooth LE RF module, and the BM70 module.
The Bluetooth LE devices include an integrated, certified Bluetooth 4.2 firmware stack. Data is transmitted over the Bluetooth link using Transparent UART mode, which you can integrate with any processor or PIC microcontroller with a UART interface. The module also supports standalone “hostless” operation for beacon applications.
The optimized power profile of these new devices minimizes current consumption for extended battery life, in compact form factors as small as 4 × 4 mm for the RF ICs and 15 × 12 mm for the module. The module options include RF regulatory certifications, or noncertified (unshielded/antenna-less) for smaller and more remote antenna designs that will undergo end-product emission certifications.
The BM70 Bluetooth Low Energy PICtail/PICtail Plus daughter board enables code development via USB interface to a PC. Or you can connect to Microchip’s existing microcontroller development boards, such as the Explorer 16, PIC18 Explorer and PIC32 I/O Expansion Board. The BM-70-PICTAIL costs $89.99.
The IS1870 Bluetooth LE RF IC (6 × 6 mm, 48-pin QFN package) costs $1.79 in 1,000-unit quantities. The IS1871 (4 × 4 mm, 32-pin QFN package) costs $1.76 in 1,000-unit quantities. The 30-pin BM70 Bluetooth LE modules are available with or without built-in PCB antennas, starting at $4.99 each in 1,000-unit quantities.
