In case you missed it – extracts from forum conversation with Swee Ann Teo, CEO of Espressif about the new chip – which I understand will have Bluetooth as well as WIFI and be a lot more powerful. Also in that discussion is a promise to support the existing chip for several years. New chip a little more expensive, existing chip a little cheaper!
“The overall architecture of the chip had been totally changed since ESP8266, and we are kind of relieved that it works….
And performance has been bumped up quite a bit! We are going to have 100Mbps sustained throughput, and EMMC interface as well. There is a lot more RAM, to go with that data rate. The same 7 external component BOM is still possible, and maybe less.
We measured about 400DMIPS on the new chip. WiFi uses less than 30DMIPS. I have no idea yet what the Hackers/Makers/Developers are going to do with that 370DMIPS and 100Mbps of data.….. we have seen hints that it can be very very low power. Low power chip design….. “
So – something to ponder – more when I know more.
