Espressif Systems first introduced ESP8285 WiFi SoC in 2016. The chip is similar to ESP8266 WiFi chip but includes 1MB flash making it more suitable for space-constrained applications since an external flash chip is not required.
Since the launch, we’ve seen several modules and final products based on the solution including ESP-WROOM-5C and PSF-A85 modules, as well as Sonoff B1 WiFI RGB light bulb.
The original chip (ESP8285N08) would work in -40°C to 85°C industrial temperature range, but in their recent newsletter, the company announced plans to launch two new variants in the ESP8285 series with an extended temperature range up to 105°C and different flash capacities:
- ESP8285H16 with 2 MB flash, -40°C to +105°C operating temperature range
- ESP8285H08 with a 1 MB flash, -40°C to +105°C operating temperature range
ESP8285H16 is slated to launch at the end of August 2019, and the company plans to provide more details next month, but I could already see both variants mentioned in the latest version of the datasheet.

They were promoting the ESP8285 as for wearables if I remember correctly. I think I have one in my collection…
Yes, but I don’t think I’ve seen one in any wearables.
