Designed for professional-grade IoT and embedded applications, it supports FreeRTOS for real-time multitasking in a sleek Feather form factor. ## Description 240 MHz dual core Tensilica LX6 microcontroller with 600 DMIPS Integrated 520 KB SRAM Integrated 802.11b/g/n HT40 Wi-Fi transceiver, baseband, stack and LWIP Integrated dual mode Bluetooth (classic and BLE) 4 MByte flash include in the WROOM32 module Review: Adafruit does it again - Great product, what you'd expect from Adafruit. It is short on pins due to the feather standard pin configuration in comparison to other esp32 boards. But with the addition of an internally only accessible(not exposed to an actual pin) analog on A13 that connects to a voltage divider and then the battery JST. That way you can monitor the battery status via analog.Read(A13). Easy to program with the Arduino IDE and available libraries or utilizing the espressif SDK you you can design your own design infrastructure. Far superior to the esp8266 feathers with 3 times faster CPU and memory not to mention the addition of an additional CPU core you can run intensive threads on core 0 and let the WiFi and main loop remain an core 1 (default Arduino CPU core) for true multitasking. Just finished a battery test that powered the unit via a 2500mAh battery with no power management for 29 hours while sending sensor data for 4 devices via MQTT every 10 seconds, add a little deep sleep and this should be extendable to a month or more depending the frequency of the wake period and the sensors powered. Bought 2 and I'm already ordering 3 more... Review: More expensive than some others but in this situation it was worth it. WLED controller. - I have picked up a few other ESP32's for different projects but sadly the one that was running my WLED setup just was not working correctly. Not sure what was wrong with the other board but after months of trying to trace down the problem and wrack my brains I decided to swap it out. Once I installed WLED on this board and set a few parameters I swapped it out with the old ESP32 I had and things just plain worked where previously it would hang over and over again with the same setup this one just chugs along. I have it controlling 1240 RGB addressable LED's (WS2812B's) that are wrapped around my front porch. I use HomeAssistant running on an Odroid N2+ to control the WLED install and it so far has not had ANY issues at all over the last couple of months. If you are doing a large addressable LED install or have had issues with stability using another ESP32 I recommend biting the bullet and grabbing one of these ones instead of constantly dealing with issues. ## Features - 240 MHz dual core Tensilica LX6 microcontroller with 600 DMIPS - Integrated 520 KB SRAM - Integrated 802.11b/g/n HT40 Wi-Fi transceiver, baseband, stack and LWIP - Integrated dual mode Bluetooth (classic and BLE) - 4 MByte flash include in the WROOM32 module ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01NCRYHDL | | Best Sellers Rank | #3,833 in Single Board Computers (Computers & Accessories) | | Brand | Adafruit | | Built-In Media | Regulator, Protection diodes, Two buttons, LED | | CPU Model | Tegra | | CPU Speed | 240 MHz | | Compatible Devices | Feather Wings | | Connectivity Technology | Wi-Fi | | Customer Reviews | 4.4 out of 5 stars 101 Reviews | | Item Dimensions L x W x H | 2"L x 0.9"W x 0.2"H | | Item Weight | 5 Grams | | Manufacturer | Adafruit | | Memory Storage Capacity | 4 MB | | Mfr Part Number | 3405 | | Model Name | HUZZAH32 | | Model Number | 2058 | | Operating System | FreeRTOS | | Processor Brand | Espressif | | Processor Count | 2 | | Processor Speed | 240 MHz | | RAM Memory Technology | SRAM | | Total Usb Ports | 1 | | UPC | 602401813243 | | Wireless Compability | Bluetooth | ## Product Details - **Brand:** Adafruit - **Model Name:** HUZZAH32 - **Memory Storage Capacity:** 4 MB - **CPU Model:** Tegra - **Connectivity Technology:** Wi-Fi ## Images ![Adafruit HUZZAH32 – ESP32 Feather Board - Image 1](https://m.media-amazon.com/images/I/51TuKuNA7lL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Adafruit does it again *by W***. on October 26, 2018* Great product, what you'd expect from Adafruit.

I think was both defective. The IDE does not connect. The red LED blinks 5 times and pauses all the time. Be shure you use the right usb cable.
