Device specifications
The name NSPanel is based on the fact it consists of parts of 2 brands of ITEAD: Nextion and Sonoff. The screen is a 3.5″ Nextion screen and the smarthome part is the Sonoff part.
These are the specifications we figured out so far:
| Microcontroller | Espressif ESP32 |
| Operating system | FreeRTOS |
| Screen | 3.5″ Nextion TFT Display, model TFT35480320TN_Z01, 165 PPI, resolution 480 x 320 pixels I wasn’t able to find more details other than the data above ITEAD provided me by email. |
| Temperature measurement range | -20 ~ 100°C Although the device working temperature is 0 – 40 °C |
| Input | 100 – 240V 50 / 60 Hz Max 4A |
| Output (normal) | 100 – 240 V 50 / 60 Hz Max 2A per channel Max 4A total |
| Output (LED) | For 110V systems: max 150W/channel, max 300W total For 240V systems: max 300W/channel, max 600W total |
| Number of channels | 2 |
| WiFi | 802.11b/g/n 2.4 Ghz only WiFi 4 |
| Color | Dim gray |
| Dimensions | EU model: 86 x 86 x 41.7 mm US model: 120 x 74 x 41.7 mm |
Although I have no experience with third party firmware I believe the Sonoff NSPanel will be capable to run third party or own written firmware as the device runs on an Espressif ESP32 chip and Nextion is easy to integrate in an Arduino sketch. So the Sonoff NSPanel might be able to run Tasmota and other firmwares.
