ESP-WROOM-5C is a Side-Mounted ESP8285 WiFi Module


Seems we don’t have enough ESP8266 or ESP8285 WiFi modules in the market, and based on an FCC listing, we now know that Espressif Systems has been working on another ESP8285 WiFi module – ESP-WROOM-5C – designed to be side-mounted on a PCB.

ESP-WROOM-5C specifications:

  • SoC – Espressif Systems ESP8285
  • Wi-Fi802.11 b/g/n WiFi 4 @ 2412 MHz ~2462 MHz;
  • Station/SoftAP/SoftAP + Station modes
  • WPA/WPA2 security with EP/TKIP/AES encryption
  • PCB antenna
  • Peripheral interfaceI2C/IR Remote Control
  • Operating voltage – 2.7V ~ 3.6V
  • Operating current – Average: 80 mA
  • Minimum current delivered by power supply – 500 mA
  • Dimensions – 19 x 16 x 3.2 mm
  • Temperature Range – -40°C ~ 105°C
  • Reliability Tests – HTOL/HTSL/uHAST/TCT/ESD

The module supports firmware upgrade over UART or OTA (Over-The-Air). Software development can be done with the IDF SDK for custom firmware, but “Cloud Server development” is also possible, and an Android/iOS app can be provided for user configuration.

There isn’t more information about ESP-WROOM-5C publicly available and you can find the user manual (PDF) for more technical details.
