[Peak-T2.0] 2.0-inch touch screen small terminal based on ESP32

Project Links：[https://gitee.com/forairaaaaa/peak-t2](https://gitee.com/forairaaaaa/peak-t2) The PCB is a 4-layer board, and the circuit and layout are basically the same as the original Peak of Zhihuijun. * Project files can be opened in the Editor Open in the upper right corner, and you may need to log in. * There is no BOM for the time being, please forgive me. #### Hardware configuration: | Master control | ESP32-PICO-D4 | | --- | ------------- | | Screen | ST7789 IPS 2.0-inch LCD SPI interface Resolution: 240x320 | | Enter the device | CST026 2.0 inch capacitive touch screen Resolution: 240x320, rotary encoder | | Output device | A user LED, buzzer | | Stockpile | TF card slot SPI interface | | IMU | MPU6050 I2C interface | | GPS | ATGM336H module UART interface | | Battery | Li-ion 3.7V 603450 1200mAh | | Power management | ME6215C33M5G + MCP73831 | | USB interface | Type-C block, CP2102 automatic download circuit | #### Welding Recommendations: * Due to the ESP32-PICO-D4 package problem, it is recommended to use a stencil with a heating platform or air gun. * It is recommended to use a soldering iron to reinforce the rotary encoder pad, which is easy to solder instability only after soldering through an ordinary heating table (don't ask how you know. #### Attention Questions: * **You need to connect the battery when burning the program, otherwise there will be a voltage problem error when burning.** * **When burning the program, you need to keep the encoder pressed to power the chip.** * Since there are several components next to the battery holder, be careful when pulling the battery plug, and don't smooth down the small devices next to it. * The chip power enable resistor on the bottom layer of the PCB uses 0603 package, which is indeed not as convenient as 0402 (it can be directly connected to tin) * If the GPS module is not needed, you can not solder, or replace your own small module, pay attention to the relevant pin problems, the details are explained in the schematic. * In the same way, MPU6050 and touch screen can also be cropped, and the two use the same set of I2C buses. #### Device Link Reference: * Battery:[Brown Navigation Dash Cam Lithium Battery Large Capacity Universal 3.7V Polymer Tire Pressure Bluetooth Headset 5V-tmall.com Tmall](%5Bhttps://detail.tmall.com/item.htm?id=579820162048&spm=a1z09.2.0.0.5eaf2e8dkwSGBJ&_u=b2bdtj0f1990%5D(https://detail.tmall.com/item.htm?id=579820162048&spm=a1z09.2.0.0.5eaf2e8dkwSGBJ&_u=b2bdtj0f1990)) Category: High temperature resistance 80 degrees -603450-1200 mAh * Shell fixed copper pillar:[M2*4/5/6/8/9/10/11/12 Dual-pass monitoring copper pillar knurled security copper pillar (10pcs)-Taobao (taobao.com)](%5Bhttps://item.taobao.com/item.htm?spm=a1z09.2.0.0.5eaf2e8dkwSGBJ&id=555117890802&_u=b2bdtj0fff40%5D(https://item.taobao.com/item.htm?spm=a1z09.2.0.0.5eaf2e8dkwSGBJ&id=555117890802&_u=b2bdtj0fff40)) Category: Dual pass M2*4 * GPS Module:[ATGM336H GPS Beidou Dual-Mode Module Flight Controller with EEPROM Replacement NEO-M8N-Taobao (taobao.com)](%5Bhttps://item.taobao.com/item.htm?spm=a1z09.2.0.0.5eaf2e8dkwSGBJ&id=595353912203&_u=b2bdtj0f9a41%5D(https://item.taobao.com/item.htm?spm=a1z09.2.0.0.5eaf2e8dkwSGBJ&id=595353912203&_u=b2bdtj0f9a41)) * LCD screen:[2 inch LCD display, 2.0 inch display HD IPS display, ST7789 driver SPI/parallel port, 240320-Taobao (taobao.com)](%5Bhttps://item.taobao.com/item.htm?spm=a1z09.2.0.0.5eaf2e8dkwSGBJ&id=653306169973&_u=b2bdtj0faa53%5D(https://item.taobao.com/item.htm?spm=a1z09.2.0.0.5eaf2e8dkwSGBJ&id=653306169973&_u=b2bdtj0faa53)) * Capacitive touch screen:[2 inch CTP capacitive touch screen 2.0 inch small size touch screen FT6236U FT6336G CST026-Taobao (taobao.com)](%5Bhttps://item.taobao.com/item.htm?spm=a1z09.2.0.0.5eaf2e8dkwSGBJ&id=607113397517&_u=b2bdtj0f8e5c%5D(https://item.taobao.com/item.htm?spm=a1z09.2.0.0.5eaf2e8dkwSGBJ&id=607113397517&_u=b2bdtj0f8e5c)) * CP2102 can be replaced with CH9102X.
