Espressif ESP32 was launched last year as a faster and upgraded version of ESP8266, with a dual core processor, 802.11 b/g/n WiFi and Bluetooth 4.0 LE. Boards based on the processor are still priced much higher than the ones based on ESP8266 ( although we’re only talking about $20 here), and shops have trouble keeping stocks, so either there’s a huge demand, there’s some manufacturing bottleneck, or maybe Espressif wants to take it slow at the beginning in case some hard to find bugs are found in the Silicon. Nevertheless, the guys at Zeptobar got hold of some ESP32 modules, and took some pretty die-shots.
The die size is 2960×2850 µm. The prettiest part is clearly the RF section zoomed in below.
If you wonder how it compares to ESP8266 die-shot, Zeptobar has you covered.

8GBP for an esp8266-01 module? https://www.coolcomponents.co.uk/en/wifi-serial-transceiver-module-w-esp8266.html
@theguyuk
Apart the Sparkfun board, none of your links are for development boards by the way… only SoCs or modules.
