Microchip rollsout Bluetooth Low Energy solutions to streamline next-gen IoT Development

Bluetooth Low Energy (BLE) solutions

Microchip Technology announces two next-generation Bluetooth Low Energy (BLE) solutions with an easy-to-use ASCII-style command interface for easy device configuration & eliminating any complicated code compiling.

Both the new rollouts named RN4870 and RN4871 supports the latest Bluetooth 4.2 specification and have a Bluetooth stack on board with a scripting engine to enable standalone operation and eliminate microcontroller (MCU) use for simple applications.

Among the key nuggets

  • These next-generation Bluetooth devices enable fast time to market and improve the total manufacturing cost.
  • Both the devices deliver up to 2.5 times the data throughput improvement over previous generation products based on the Bluetooth 4.0 standard. In addition, the new Bluetooth solutions offer Federal Information Processing Standards (FIPS) based connection security coupled with advanced features.
  • The devices can seamlessly transfer serial data over BLE devices and can support different beacon formats like iBeacon or Eddystone via a single command.
  • Both devices with a shield option are fully certified to meet worldwide regulatory standards and are available with compact package options as small as 6 x 8 mm.

“This latest offering from Microchip will ultimately enable Internet of Things (IoT) developers to build better end applications with lower power consumption,” said Steve Caldwell, vice president of Microchip’s Wireless Solution Group. “With our products, developers can reduce design complexity and shorten time to market significantly. These new RN-style modules are the easiest way for customers to get started with Bluetooth Low Energy solutions in their products.”

“Microchip was the first to offer Bluetooth 4.2 compliant silicon, modules and software” adds Caldwell. “We are proud to be a leader in Bluetooth technology.”

Each module has an on-board software stack and pairs well with any of Microchip’s large range of low-power microcontrollers or any microcontroller with a UART interface. The RN4870 and RN4871 are designed to complement Microchip’s diverse low-energy solutions designed for IoT applications.


  • The RN4870-V/RM118, which is shielded with an onboard antenna, is obtainable for sampling and volume production in a 12 x 22 mm module in 1,000-unit quantities. The
  • RN4870U-V/RM118, which is unshielded with an external antenna, is obtainable for sampling and volume production in a 12 x 15 mm module in 1,000-unit quantities.
  • The RN4871-V/RM118, which is shielded with an onboard antenna, is obtainable for sampling in a 9 x 11.5 mm module in 1,000-unit quantities. The RN4871U-V/RM118, which is unshielded with an external antenna, is also obtainable for sampling in a 6 x 8 mm module in 1,000-unit quantities.

Development support

Also available from Microchip is the RN4870 Bluetooth 4.2 Low-Energy PICtail/PICtail Plus Daughterboard with a sensor board (part # RN-4870-SNSR). The board is available today.

In addition, several existing interfaces will be supported by the RN4870 and RN4871 including the PIC18 Explorer Board (DM183032), the Explorer 16 Board (DM240001/2), and the PIC32 Expansion Board (DM320002).
