Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/DFR0654:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description FireBeetle ESP32-E, specially designed for [IoT](https://www.dfrobot.com/topic-276.html), is an ESP-WROOM-32E-based main controller board with dual-core chips. It supports WiFi and Bluetooth dual-mode communication and features a small size, ultra-low power consumption, on-board charging circuit, and easy-to-use interface, which can be conveniently used for smart home IoT, industrial IoT applications, wearable devices, and so on. You can easily create your own IoT smart home system when connecting it with an IoT platform like IFTTT. FireBeetle ESP32-E supports [Arduino](https://www.dfrobot.com/topic-277.html) programming and will support Scratch graphical programming and MicroPython programming very soon. We provide you with detailed online tutorials and application cases, and there are thousands of sensors with welding-free Gravity interface and actuators to help you get started easily. Besides, the stamp hole design makes it able to be easily embedded in your [PCB](https://www.dfrobot.com/category-135.html), greatly saving your costs and time to build and test prototype. **Note:** The USB to Serial chip driver used on this FireBeetle is not compatible with MAC OS systems. ![](https://core-electronics.com.au/media/wysiwyg/product_images/dfr0654-overview.jpg) ![](https://core-electronics.com.au/media/wysiwyg/product_images/dfr0654-pinout_1.jpg) ### Features - ESP32 Dual-core low power maincontroller, 10uA power consumption - WiFi Bluetooth 4.0 Dual-mode Module - GDI Display Port, easy to connect - Onboard Charging Circuit and PH2.0 lithium Battery Interface ### Specification - Operating Voltage: 3.3V - Input Voltage: 3.3V~5.5V - Support Low-Power: 10uA - Max Discharge Current: 600mA@3.3V LDO - Max Charge Current: 500mA - Support USB Charging - Processor: Tensilica LX6 dual-core processor (One for high-speed connection; one for independent application development) - Main Frequency: 240MHz - SRAM: 520KB - Flash: 16Mbit - Wi-Fi Standard: FCC/CE/TELEC/KCC - Wi-Fi Protocol: 802.11 b/g/n/d/e/i/k/r (802.11n,speed up to 150 Mbps), A-MPDU and A-MSDU Aggregation, support 0.4us guard interval) - Frequency Range: 2.4~2.5 GHz - Bluetooth Protocol: Bluetooth v4.2 BR/EDR and BLE standard compliant - Bluetooth Audio: CVSD and SBC audio - Operating Current: 80mA(Average) - Support Arduino download with one-key - On-chip Clock: 40MHz crystal, 32.768KHz crystal - Digital I/O x10(Arduino default) - Analog Input x5(Arduino default) - SPI x1(Arduino Default) - IIC x1(Arduino Default) - I2S x1(Arduino Default) - RGB\_LED: 5/D8 - Connector: FireBeetle V2 series compatible - Operating Temperature: -40°C ~ 85°C - Module Size: 25.4×60mm/1×2.36” - Mount Hole Size: inner diameter of 2.0mm **Documents**- [Product wiki](https://wiki.dfrobot.com/FireBeetle_Board_ESP32_E_SKU_DFR0654) ### Parts List - FireBeetle Board ESP32-E x1 - 18pin-2.54mm Pitch Pin x1 - 18pin-2.54mm Pitch Pin Female x1 - 14pin-2.54mm Pitch Pin x1 - 14pin-2.54mm Pitch Pin Female x1 ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/d/f/dfr0654.jpg)
