It inherits all functions of Romeo BLE. Moreover, IT GOT A SMALLER SIZE! Yes, you got it all. It has 8 Digital pins, 4 analog pins and integrates Bluetooth 4.0 wireless communication function. And it can easy to drive the mobile platform using two 1.2A H-bridged Motor Driver to meet the needs of small scale robots. We hope Romeo BLE mini will be a good assistant to makers. You may also check Bluetooth Microcontrollor Selection Guide to get more information. \u003cbr\u003e\u003cbr\u003e\u003cb\u003e\nVersion Update:\u003c\/b\u003e V2.0 has upgraded its motor driver IC, it replaces HR8833 with TB6612 motor driver chip. TB6612 has the same control logic with L298 motor driver. The code will be compatible with Romeo robot control board. And it finally breakouts 2 interrupt pins now! You can connect encoders to make PID motor control.\u003cbr\u003e\n\u003cdiv style=\"text-align:center\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:center\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003eRomeo BLE mini Projects:\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003eHow To Make an Arduino compatible Bluetooth Tank with Custom Android Application (V1.0)\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003eHow to Build a BB-8 Robot\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003eHow to Build a Smartphone-Controlled Robot for Arduino In Only 1 hour\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\nHow to make a Wobbly Penguin Robot for Arduino\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e \u003ch2\u003e Features\n\u003c\/h2\u003e \u003cdiv class=\"desCon\"\u003e\n\u003cul\u003e\n\u003cli\u003eSupport Gravity-3Pin interface, color-coded, compatible with servos and Gravity sensors \u0026amp; modules\u003c\/li\u003e\n\u003cli\u003eSupport external power supply automatically switch, can simultaneously USB and external power supply\u003c\/li\u003e\n\u003cli\u003eSupport wireless download program \/ wireless communication function\u003c\/li\u003e\n\u003cli\u003eSupport mobile phone APP control\u003c\/li\u003e\n\u003cli\u003eTwo-way H-bridged Motor Driver\u003c\/li\u003e\n\u003cli\u003eSupport servo external power input\u003c\/li\u003e\n\u003cli\u003eSupports AT commands to configure BLE\u003c\/li\u003e\n\u003cli\u003eSupport serial transmission\u003c\/li\u003e\n\u003cli\u003eSupport master and slave switch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e \u003ch2\u003e Specification\n\u003c\/h2\u003e \u003cdiv class=\"desCon\"\u003e\n\u003cul\u003e\n\u003cli\u003eBLE chip: TI CC2540\u003c\/li\u003e\n\u003cli\u003eTransmission distance: 30m (open area) \u003c\/li\u003e\n\u003cli\u003eMicroprocessor: ATmega328P\u003c\/li\u003e\n\u003cli\u003eBoard selection: Arduino UNO\u003c\/li\u003e\n\u003cli\u003eFlash: 32 KB (ATmega328P) of which 0.5 KB used by bootloader\u003c\/li\u003e\n\u003cli\u003eSRAM2: KB (ATmega328P) \u003c\/li\u003e\n\u003cli\u003eEEPROM: 1 KB (ATmega328P) \u003c\/li\u003e\n\u003cli\u003eClock Frequency: 16 MHz\u003c\/li\u003e\n\u003cli\u003eDigital I\/O Pins: 8\u003c\/li\u003e\n\u003cli\u003ePWM Digital I\/O Pins: 4 (D3, D9, D10, D11) \u003c\/li\u003e\n\u003cli\u003eAnalog Input Pins: 4\u003c\/li\u003e\n\u003cli\u003eOutput current: 1.2A single-channel continuous drive current\u003c\/li\u003e\n\u003cli\u003eStart \/ Peak Current: 2A (continuous pulse) \/ 3.2A (single pulse) \u003c\/li\u003e\n\u003cli\u003eMotor Drive Pins: D4, D5, D6, D7\u003c\/li\u003e\n\u003cli\u003emicroUSB connector\u003c\/li\u003e\n\u003cli\u003e2x2A H-bridge motor driver\u003c\/li\u003e\n\u003cli\u003eSize: 45x38.5mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e \u003ch2\u003e Documents\u003cbr\u003e\n\u003c\/h2\u003e \u003cdiv class=\"desCon\"\u003e\n\u003cli\u003eRomeo BLE Mini V2 WIKI\u003c\/li\u003e\n\u003cli\u003eRomeo BLE Mini V1 WIKI\u003c\/li\u003e\n\u003cli\u003eMore Documents\u003c\/li\u003e\n\u003c\/div\u003e \u003ch2\u003e Shipping List\u003cbr\u003e\n\u003c\/h2\u003e \u003cdiv class=\"desCon\"\u003e\n\u003cul\u003e\n\u003cli\u003eRomeo BLE mini V2.0 x1\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e \u003c\/div\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":48623718695130,"sku":"eqr1789676857626","price":23.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/romeo-ble-mini---small-control-board-for-robot---arduino-compatible---bluetooth-_1.jpg?v=1789676863","url":"https:\/\/memoryfoamwear.shop\/products\/romeo-ble-mini-small-control-board-for-robot-arduino-compatible-bluetooth-40","provider":"My Store","version":"1.0","type":"link"}
