Capacitive Touchscreen TFT LCD 3.5-inch with Controller Board

Model No. RFC350X-EYW-DBG

RFC350X-EYW-DBG is one of the models in our Q series—3.5-inch IPS TFT LCD display module with controller board and PCAP touch. The resolution of this module is 320 x 240 pixels, and it has 4 screw holes & metal frame allowing for quick mounting.

The Q series mainly uses IC SSD1963. TFT modules of this series are all characterized by 36-pin MCU 8080 8/16-bit pin define, and the 8/16-bit 6800 pin define interface can be selected through Jump. Compared to the P series, functions of Q series are simple and pricing is relatively lower.

The brightness is 400 cd/m2 with contrast ratio 800:1. LCM voltage ranges from 3.0V-3.3V, typical value is 3.1V. Operating temperature covers from -20~+70℃, storage temperature range is from -30~+80℃.
