In case you’ve been hiding under a virtual rock over the last two years, you might have missed it when Espressif turned the IoT game on its head by releasing a chip with WiFi and a decent embedded processor for under $1 in bulk, and costing not much more than that in a module.
They’re looking to repeat the success of the ESP8266 with the ESP32, that should be coming out any time now. As we get closer to the release date, details start to dribble out. [Alberto], who makes very nice-looking pinout diagrams for a number of our favorite chips and modules, has already made us an ESP32 module pinout diagram.
And [Rudi] has been digging up nearly every crumb of info on the ESP32 that’s publicly available. For instance, it was through his website that we learned that the new RTOS SDK source is already up on GitHub.
There’s also a source of official information in the ESP32 forum, but there’s not much news there just yet. We expect this to change as more beta units make it out into the wild.
We covered the announcement of the forthcoming ESP32 last month, and we have to say that we’re looking forward to getting a module or two in our hands. Twin cores, BTLE support, and better DMA are tops on our list of neat features.
