This Bluetooth controller combines Bluetooth Low Energy 4.1 with Arduino controller, offering functions similar to the former Bluno series but with lower power consumption.    FireBeetle BLE 4.1 is compatible with Bluno series (BLE 4.0) and performs much better. It equipped with more stable DIALOG Bluetooth 4.1 chip, supporting maximum 4Kbyte/s transmission rate and low power consumption (25uA POWER DOWN). It can be directly applied to low power consumption application such as wearable and intelligent tools and so on.   It also supports multiple Bluetooth cascade, KISS connection (approach connection) and compatible with Bluno series. Its connection can be realized by holding host BOOT and moving to the target peripheral device.           FEATURES         \tSupport Arduino IDE program \tSupport BLE 4.1 central and peripheral switch \tSupport Bluetooth serial port data transmit \tSupport Bluetooth peer to peer (P2P) wireless programming \tSupport Bluetooth 4.1 multiple device cascade (maximum:4) \tSupport Arduino Bluetooth library (support multiple Bluetooth connection) \tSupport low power consumption Bluetooth (standby current: 25uA; enabled interrupt current: 70uA) \tDouble interruption to wake up: \tBLE4.1 awake Atmage328P by D2 (high level awake) \tAtmage328P awake BLE4.1 by D3 (low level awake) \tSupport KISS connection (approach connection) \tSupport Bluetooth firmware update \tSupport USB charge \tSupport lithium battery power supply \tEquipped with status LEDs           SPECIFICATION         \tProcessor: ATMEGA328P \tBootloader: Arduino Pro or Pro Mini, ATmega328 (3.3V, 8MHz) \tOperating Current: 3.3V \tVCC I/O Voltage: 3.7V~5.5V \tLithium Battery Voltage: 3.7V \tSupport maximum 4Kbyte/s transmission rate (more device, lower rate) \tSupport low power consumption: 25uA (POWER DOWN); 70uA (enabled interruption) \tSupport maximum discharge current: 600mA (LDO-3.3V OUTPUT) \tSupport maximum charge current: 400Ma \tDigital Interfaces: 14 \tAnalog Interfaces: 6 \tSPI: 1 \tI2C: 1 \tUART: 1 \tLED_BUILTIN: D13 \tInterface Mode: 2.54mm (Pin/Female header), soldering free in default \tDimension: 58 * 29 mm/ 2.28 * 1.14 inches           DOCUMENTS         \tProduct wiki \tMore Documents  \n\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":6708,"title":"Default Title","sku":"DF-DFR0492","price":32.0,"on_sale":false,"in_stock":true,"available_quantity":97,"option1":"Default Title"}]}
