Espressif ESP32-DevKitC-VIE Development Board with ESP32-WROVER-IE, 4 MB Flash, 8 MB PSRAM, USB, Bluetooth, 802.11 N, FreeRTOS, 240 MHz CPU

This is the new ESP32-DevKitc_V4-VIE development board from Espressif. It has only been available for purchase for a few months. It is the latest iteration of the WROVER models that have the additional 8 megabytes of PSRAM (but only 4 MB can currently be used). Until now I have only seen these Espressif development boards offered with 4 megabytes of program flash memory. This model has double that -- 8 MB! So twice the memory and an extra 4 MB of usable PSRAM! To see details of the different ESP32s, google "Espressif Product Ordering Information." Based on that source, this WROVER-VIE uses the new ESP32-D0WD-V3 chip. It has an IPEX (ergo the "I" in "VIE") connector for an external antenna, as well as an onboard PCB antenna that is disabled. It is possible to convert it to use the onboard antenna, but that involves doing some micro-soldering to remove a tiny 0 ohm resistor and add a tiny solder bridge. So if you want to use the onboard antenna, I strongly suggest you order the VE (no "I") version that Amazon sells for the same price: https://www.amazon.com/Espressif-ESP32-DevKitC-VE-Development-Board/dp/B087TNPQCV Here is an example of an external antenna that works well https://www.amazon.com/gp/product/B01KBU61S8 Features: 240 Mhz CPU (configurable) 80 Mhz Flash (configurable) IPEX connector for external antenna (buy the “VE” version if you want to use the onboard PCB antenna) OTA upgradeable PROs: Great price – only $11.00 8 Megabytes of flash memory 8 Megabytes of PSRAM (but only 4 Megabytes can be used) Quality build Does not require that you manually put it in boot loader mode before flashing CONs: Due to its width, when installed in a breadboard, only one row of exposed pin sockets are available I have used multiple models of the Espressif Esp32-devkitc_v4 development boards in the past and have been happy with them all. This one is my new favorite.

Arrived relatively on time. Both seem to be working fine. The ESP32 has a lot of features: SPI tested OK, SDIO tested OK, I2C tested OK, UART tested OK, WiFI OK. Something to look out for is that its fuses were different from the original DevKitC boards. In my opinion, because these boards come pre-built with SPI flash, then the respective fuses should have been pre-burned so that you don't get strapping pin issues with your SD-Card. The thing seems to be working fine. They are GREAT, feature-filled little development boards for the price. (There is a learning curve for the ESP-IDF development, but the NET is full of tutorials.) They are more expensive from Amazon (double or more), but at $11.00, the price is still good for what you get. I'm very pleased with them so far.

There’s nothing like buying the genuine article. Sadly, there are a lot of knockoffs on this website, but this board is the real deal. I’m happy to say this ESP32 has been a joy to use and performs exactly to spec. It’s fast, reliable, and has excellent Wi-Fi and Bluetooth performance — exactly what you would expect from a genuine product. If you’re tired of unreliable clones and inconsistent quality, this is absolutely worth It!

Il s'agit d'un modèle officiel ESPRESSIF, ESP32 DEVKIT-C VIE, c'est le même que le VE à l'exception près qu'il y a ici la possibilité d'ajouter une antenne externe. Ce modèle est vraiment parfait car il possède une mémoire flash de 8Mo et 4mo de mémoire vive supplémentaire (PSRAM). Je l'utilise pour faire fonctionner une machine complexe composée de multiples moteurs. A force de créer des TASK FREERTOS (Espressif framework IDF), la mémoire finissait pas se saturer. J'ai modifié l'implémentation pour utiliser la PSRAM et je n'ai plus aucun problème. La carte respire la rigueur et la robustesse, un bon produit que je recommande fortement.
