Adafruit1.8" TFT LCD shield扩展板

STM32 NUcleo可以支持这个扩展板

想参考一下他的原理图重新做个PCB 有用过这个板子的么？

官方的介绍：
Specifications:

1.8" diagonal LCD TFT display
Physical dimensions: 2.71" (69mm) width, 2.1" (53.5mm) height, 0.27" (6.94mm) thickness (top of joystick)
128x160 resolution, 18-bit (262,144) color
ST7735R (datasheet) controller with built in pixel-addressable video RAM buffer
4 wire SPI digital interface
Built-in microSD slot - uses 2 more digital lines
5V compatible! Use with 3.3V or 5V logic Arduinos
Onboard 3.3V @ 150mA LDO regulator
2 white LED backlight, transistor connected. Defaults to 'on' but can be connected to a digital pin for PWM or simply turning off
Comes with header, requires soldering!
Display current draw is mostly based on the backlight, with full backlight the current draw is ~100mA, this does not include the SD Card. SD cards can draw 20-100mA based on read/write. Measure current draw in circuit to get precise numbers.
完全可以根据现有的屏自己设计，要用他的驱动库就得找能兼容的屏了
