{"title":"BlueSMiRF v2 Bluetooth Serial Link with JST-GH","handle":"sparkfun-bluesmirf-v2-jst","url":"/products/sparkfun-bluesmirf-v2-jst","description":"Turn a wired UART link into a dependable short-range Bluetooth® serial connection for microcontrollers, computers and mobile devices. It pairs, connects and passes data between TX and RX lines, buffering serial streams for byte-perfect delivery between radios.This JST version swaps the usual pins and headers for a 6-pin JST-GH connector. It shares the same pinout and connector as the SiK Telemetry Radio V3 and SparkFun LoRaSerial Kit, making it a drop-in style option where you want Bluetooth rather than an RF telemetry link.It is especially useful with high-precision GNSS breakouts such as LG290P, mosaic-G5 P3, ZED-X20P and LG580P, letting you stream positioning data to a GIS app on a phone. Bluetooth Classic SPP is the primary protocol for Android and most desktops/laptops, while BLE support helps with Apple and low-power devices.SparkFun documentation and design resources include schematic, KiCad files, 3D model, board dimensions, hookup guide, ESP32-PICO-MINI-02 datasheet, ESP32 technical reference manual, firmware and hardware repository files.Features:Module: Espressif's ESP32-PICO-MINI-02 Module with Built-in PCB AntennaSerial link: Serial Bluetooth® Point-to-Point CommunicationBluetooth Protocols Supported: Serial Port Profile (SPP)Bluetooth Protocols Supported: Bluetooth Low Energy (BLE)Firmware updates: Firmware Over-the-Air (OTA) Updates via 2.4GHz WiFiSimple Pairing: Connecting two BlueSMiRFs is as simple as pressing the onboard PAIR button.Phone and computer connection: You can also connect directly to a phone or computer for remote control and data viewing.Remote Configuration: Use a serial terminal app and a simple AT command set to adjust baud rates, flow control and LED modes on the fly.Power and Logic: Onboard AP2112K voltage regulator and logic-level shifting make all pins 3.3V to 5V-tolerant.Status monitoring: Built-in status LEDs monitor connection and serial traffic.Specifications:Wireless serial stream: 2400 to 921600 baudFull-duplex transmission: Up to 921600 bpsShort-range indoor operation: Up to 100 feet (33 meters)Connector: 6-pin JST-GH connectorPinout compatibility: Same pinout and connector as the SiK Telemetry Radio V3 and the SparkFun LoRaSerial KitRecommended Input Voltage: 3.3V to 5VCurrent & Power Consumption @ 3.3V - Idle: 72mA / 238mWCurrent & Power Consumption @ 3.3V - Connected with no Serial Traffic: 75mA / 248mWCurrent & Power Consumption @ 3.3V - Constant Duplex Serial Traffic: 140mA / 462mWVoltage Regulator: AP2112K 3.3V/600mA Voltage RegulatorLogic Level Converters: on all pinsPin tolerance: All pins 3.3V to 5V-tolerantHigher voltage serial: RS232-to-TTL converter is required for higher voltagesStandard Serial Port with JST-GH connector: RTS/RXI/TXO/VCC/CTS/GNDPTH: ResetButton: PairLED: CONNECTLED: STATUSJumper: 3.3V Bypass Jumper (JP2)Jumper: Pair Button (BTN)Board Dimensions: 40.8mm x 15.22mm (1.60\" x 0.60\")Weight: 3.40gA handy cable-cutting board for GNSS, telemetry, robotics and embedded projects where you need a simple Bluetooth UART bridge.","vendor":"SparkFun","product_type":"Bluetooth Serial Module","in_stock":true,"options":[],"variants":[{"id":15578,"title":"Default Title","sku":"SF-WRL-30414","mpn":"WRL-30414","price":23.9,"on_sale":false,"in_stock":true,"available_quantity":126}]}
