HiLetgo 2.2 inch TFT LCD Display Shield Touch Panel ILI9341 4-Wire Serial Port Module for Arduino UNO MEGA 51/AVR/STM32/ARM/PIC

Got three of them all working(1 with Arduino Leonardo and 2 with NodeMCU ESP8266). arduino will need a solution to the 5v out 3.3v in(10s solder job) NodeMCU is directly compatible. i used adafruits code. Very happy. getting more. also hiletgo products have all been functional so far. becoming a fan. Update: switched to TFT_eSPI.h library. Wow. Orders of magnitude faster display now. A bit trickier to setup but well worth it.

パネルが外れかけていたが瞬間接着剤で修復して問題なし。 信号系は3.3V。Arduinoから使用するにはレベル変換が必要。 Adafruitsのライブラリで映るが、GithubのPDQ_GFX_Libsを使用すると描画速度が5~10倍になる。 これだけ速度が出ればよいだろう。 追記：今見たら2680円になっていた。それだけの金額の価値はない。 私は680円で購入した。上記レビューは680円の前提。

For the price, this is probably highest quality screen you're going to get, the colors and brightness are decent and it's a breeze to wire to Arduino, ESP32 and RPi. I've used dozens of these without many issue. My only complaint is that I wish they would offer a model w/o the SD card reader and w/o the header pins pre-installed.

Works great with ILI9340 driver library for PIC32. No problems running SPI bus at 30Mhz, but glitches past 34Mhz to no response at 40Mhz for those wondering about max transfer speed for drawing. Very responsive at 20Mhz+ Hardware SPI clock.

中国発なので心配したが商品は予定よりも１０日も早く到着した。梱包も丁寧で、商品も作動良好です。
