2. The street price of ESP8266 seems to be $6.49, which is more then $4.00. I imagine the rpi board uses less current, and the programable logic in the gpio's gives some interesting opportunities.
- sargun 6y agoOr, the ESP32-C3, which is <$2.
- alexhutcheson 6y agoThat's just the chip, not the board.
- sargun 6y agoThe dev board (WROOM) is an additional $2.
- alexhutcheson 6y agoLink? The dev boards I’m familiar with are $10. Not that I really care for hobby purposes - I’m not buying 100s of them.
- sargun 6y agoThere's no publicly released pricing AFAIK, since the board is still in preproduction. I think the dev board is more expensive -- and targeted to be $8. $8 for a board with WiFi is pretty good.
- jascii 6y agoI haven't benchmarked them, but the ESP32-C3 only has a single core, right? I also assume the wifi and bluetooth functionality will increase current use.
- RicoElectrico 6y agoActually, the most popular ESP32 (DevkitC) board can be had for $4 or so: https://aliexpress.com/item/4001076883280.html https://aliexpress.com/item/4001076883280.html
- tachyonbeam 6y agoWould it make the device larger? The RPi GPIO is 40 pins (2x20). This board has two 20 pin headers (40 pins total). You could have the RPi GPIO off to one side and it would take the same total area. Maybe it's not as fun to route the multilayer PCB to achieve this, but it would fit better with the existing RPi brand/ecosystem. As for the ESP8266 (not ESP32), you can find them on eBay below $3 shipped. The ESP8266 is already quite fast and capable for a microcontroller (it's overkill for many applications). I agree that more IO pins could be a differentiating factor.
