KC868-A8V3 and ESPHome firmware - JuDie07 - 11-12-2025
Question: According to the description, the KC868-A8v3 board has an ESP32-S3-WROOM-1U (N16R8) installed, right?
According to the datasheet, it is built around the ESP32-S3 series of SoCs, Xtensa® dual-core 32-bit LX7 microprocessor, flash up to 16 MB,
and PSRAM up to 16 MB, so 16 MB is installed!
Do I need to specify this in the configuration?
esp32:
board: esp32dev
flash_size: 16MB
framework:
type: esp-idf
esp32:
board: esp32-s3-devkitc-1
framework:
type: arduino

Thank you—but this does NOT answer my question about memory!

so 16 MB is installed! Yes, PSRAM is 16M

An article worth reading on this topic can be found at-> https://community.home-assistant.io/t/esp32-s3-devkitc-1-n16r8-using-psram-howto/652601
Does Kincony also have a recommendation or an adapted/revised configuration? (esphome)?

if you use home assistant, suggest download KCS v3 firmware, integrate to home assistant by mqtt auto discovery, it's easy.

HEllo, I am trying to flash the KCS_A8V3_V3.15.0.bin firmware to my Kincony KC868-A8-V1.5 board. It flash but does not boot up. What did I do wrong? I flashed with v2 it works but limited features. Can this board flash with the latest KCS_A8V3_V3.15.0.bin firmware???

A8 old pcb only use by KCS v2, can't use by KCS v3.
A8v3 board made by ESP32S3 CPU, it use by KCS v3 firmware.
