This product is a self-balancing robot composed of the M5Stack Gray and the BALA2 motor base. The base uses the STM32F030C8T6 as the main controller, powered by two N20 encoded reduction motors, and has a built-in 1200mAh battery. The name \"BALA\" comes from the abbreviation of \"Balance,\" and this is the second-generation product. The BALA2 base includes a rich set of interfaces, supporting 8 servo motors in addition to the regular PortB and PortC, with 4 interfaces directly connectable and the other 4 needing to be extended from inside the base. You can program it to move freely or develop remote control functions with WiFi. Even if you have never worked with balancing car programs before, you can quickly complete programming and control it using UiFlow. The product comes pre-installed with a balancing car application, using a PID closed-loop algorithm to maintain vertical balance during operation, and utilizes accelerometer and gyroscope attitude data to correct its direction and position.\u003c\/p\u003e\n\u003ch2 data-id=\"Features\" id=\"features\"\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e9-axis attitude sensor\u003c\/li\u003e\n\u003cli\u003eDual-wheel drive, PID control balance\u003c\/li\u003e\n\u003cli\u003eGrove expansion interface (PORTB\/PORTC)\u003c\/li\u003e\n\u003cli\u003e8 servo motor drives, 4 external, 4 internal\u003c\/li\u003e\n\u003cli\u003eSupports WiFi, programmable\u003c\/li\u003e\n\u003cli\u003eBuilt-in speaker\u003c\/li\u003e\n\u003cli\u003eSupports TF card expansion\u003c\/li\u003e\n\u003cli\u003eCompatible with LEGO\u003c\/li\u003e\n\u003cli\u003eI2C communication: 0x3A\u003c\/li\u003e\n\u003cli\u003eDevelopment platforms\n\u003cul\u003e\n\u003cli\u003eMicroPython\u003c\/li\u003e\n\u003cli\u003eUiFlow\u003c\/li\u003e\n\u003cli\u003eArduino\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Includes\" id=\"includes\"\u003eIncludes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Gray\u003c\/li\u003e\n\u003cli\u003e1 x Bala2 Base\u003c\/li\u003e\n\u003cli\u003e2 x HY2.0-4P connection cables (20cm)\u003c\/li\u003e\n\u003cli\u003e4 x wheel hub connectors\u003c\/li\u003e\n\u003cli\u003e2 x LEGO arms\u003c\/li\u003e\n\u003cli\u003e1 x hex key\u003c\/li\u003e\n\u003cli\u003e1 x USB Type-C cable (1m)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Applications\" id=\"applications\"\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBalancing car\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Specifications\" id=\"specifications\"\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"table-container\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eParameters\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMCU\u003c\/td\u003e\n\u003ctd\u003eSTM32F030C8T6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eESP32\u003c\/td\u003e\n\u003ctd\u003e240MHz dual-core, 600 DMIPS, 520KB SRAM, Wi-Fi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlash\/RAM\u003c\/td\u003e\n\u003ctd\u003e16MB Flash\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLCD\u003c\/td\u003e\n\u003ctd\u003e2-inch, 320x240 color TFT LCD, ILI9342C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpeaker\u003c\/td\u003e\n\u003ctd\u003e1W-0928\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMEMS\u003c\/td\u003e\n\u003ctd\u003eBMM150+MPU6886\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor drive\u003c\/td\u003e\n\u003ctd\u003eHR8833\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBase controller\u003c\/td\u003e\n\u003ctd\u003eSTM32F030\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterfaces\u003c\/td\u003e\n\u003ctd\u003eGROVE I2C x 1\/UART x 1\/GPIO x 1\/SERVO x 4(+4 Extendable Channels)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery capacity\u003c\/td\u003e\n\u003ctd\u003e1200mAh\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet weight\u003c\/td\u003e\n\u003ctd\u003e157.0g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGross weight\u003c\/td\u003e\n\u003ctd\u003e337.0g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Size\u003c\/td\u003e\n\u003ctd\u003e54 x 54 x 65mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackaging dimensions\u003c\/td\u003e\n\u003ctd\u003e100 x 100 x 100mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCasing material\u003c\/td\u003e\n\u003ctd\u003ePlastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eLearn and Documents\u003c\/h2\u003e\n\n  → DOCUMENTS\n\n\u003c\/div\u003e","brand":"m5stack-store","offers":[{"title":"Default Title","offer_id":53634560852261,"sku":"qml1787247203057","price":47.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0936\/6251\/1397\/files\/eol-bala2-esp32-self-balancing-robot-kit_1.jpg?v=1787247211","url":"https:\/\/www.bloomwella.com\/products\/eol-bala2-esp32-self-balancing-robot-kit","provider":"My Store","version":"1.0","type":"link"}
