The esp8266 is cheap because they used expnsive to design, cheap to produce process(40nm). Quallcom had a similar chip(QCA4004 ?), probably with similar manufacturing costs, which they sold only to big companies, probably at a higher price.
Also when you come to judge that chip, don't forget china's interests in the chip industry and in security. I wouldn't be surprised those helped the esp to become reality.
- makomk 10y agoThe ESP8266 is an ingenious little chip. It's fully integrated - no external balun required unlike many of its competitors, no calibration by board manufacturers, just drop in and use. They reached the scales required to justify their NRE costs by making it a dual-use chip that could serve both as a a WiFi interface for cheap Android tablets and a standalone IoT design.
