 When buying a new device in 2025 we can only recommend the ESP32-P4 or ESP32-S3 with PSRAM (look for an ESP32-S3 with the designation N>=4 and R>=2 such as an ESP32-S3 N16R8).<br>
 
-The ESP32-P4 with ESP32-C6-MINI-1 module for BLE/WiFi is the most powerfull ESP32 in 2025. 
+The ESP32-P4 with ESP32-C6 or ESP32-C5 module for BLE/WiFi is the most powerfull ESP32 in 2025. 
-It supports (with the C6 co-processor) anything the ESP32 range has to offer with the highest CPU clocks, largest flash and PSRAM, Ethernet, PoE and WiFi6.
+It supports anything the ESP32 range has to offer with the highest CPU clocks, largest flash and PSRAM, Ethernet, PoE and WiFi6 (and 5 GHZ WiFi with the C5 as co-processor).
-The only function missing (when not using a C5 as co-processor) is 5Ghz WiFi support.
 
 The ESP32-S3 is a dual-core CPU with many GPIO's, ability to enlarge RAM using PSRAM, ability to connect Ethernet modules over SPI and optionally power the device with a PoE splitter.<br>
-The only functions missing from the ESP32-S3 as compared to other ESP devices is the ability to use some Ethernet modules only supported by the original ESP32 (and ESP32-P4) and the ability to connect over WIFI6 (C5, C6 or ESP32-P4 with C6 module)

 The ESP32-C5 with PSRAM is a good option providing higher clockspeeds than the C6 and adding PSRAM and WIFI 6 on the 5 Ghz band support.
 Nuki Hub uses both CPU cores (if available) to process tasks (e.g. HTTP server/MQTT client/BLE scanner/BLE client) and thus runs better on dual-core devices.<br>
 
 Other considerations:
-- If Ethernet/PoE is required: ESP32-P4 with ESP32-C6-MINI-1 module or ESP32-S3 with PSRAM in combination with a SPI Ethernet module ([W5500](https://www.aliexpress.com/w/wholesale-w5500.html)) and [PoE to Ethernet and USB type B/C splitter](https://aliexpress.com/w/wholesale-poe-splitter-usb-c.html) or the LilyGO-T-ETH ELite, LilyGO-T-ETH-Lite-ESP32S3 or M5stack Atom S3R with the M5stack AtomPoe W5500 module
