Product Description

Authorized North America Distributor Stamp

The ESP32-C3FN4 SOC has 4MB flash and is the next generation replacement for the ESP8266EX SOC. This new chip makes new designs simple and is a very cost effective solution. Based on a single RISC-V core, performance has improved.

Other ESP32-C3FN4 updates include

  • advanced security
  • USB 2.0
  • BLE 5.0 with long range support
  • power management

The ESP32-C3FN4 is part of the ESP32-C3 family of parts and provides the lowest cost fully certified solution of all the Espressif parts.  

Trouble shooting is improved with on-chip debug module (DM), compliant with RISC-V debug specification v0.13. Also, an external debugger is supported using the industry-standard JTAG/USB port. The debugger provides direct system bus access (SBA) to memory and peripherals along with up to 8 trigger breakpoints/watchpoints.
