Most microSD on the Red Mcufriend mega2560 shields will not work because the Resistor Pack is the wrong value. In theory, microSD are not 3.3V input tolerant. In practice, the microSD work ok with 5V SPI. They must always have 3.3V VCC.
ER-TFT020-1 is 320x240 dots 2" color tft lcd module display with ILI9342 controller,optional 4-wire resistive touch panel ,superior display quality,super wide viewing angle and easily controlled by MCU such as 8051, PIC, AVR, ARDUINO ARM and Raspberry PI.It can be used in any embedded systems,industrial device,security and hand-held equipment which requires display in high quality and colorful image.It supports 8080 8-bit,9-bit,16-bit,18-bit parallel,3-wire,4-wire serial spi interface. FPC with zif connector is easily to assemble or remove.Lanscape mode is also available.
The cute PiTFT got even more adorable with this little primary display for Raspberry Pi in HAT form! It features a 2.2" display with 320x240 16-bit color pixels. The HAT uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top of your Model A+ or B+ and fits into Adafruit's case quite nicely.
It's designed to plug directly onto the Raspberry Pi 2 or Raspberry Pi 1 Model A+ or B+ . While not specifically designed for Pi Model A or B, you can use it with A/B if you solder in an extra-tall 2x13 header (not included) instead of the included 2x20 header
