When testing, do not remove any protective film or tags. Please pay attention to the problem of static electricity.
Before attempting any repair, be sure to ground yourself is an ESD (electro static discharge) strap. This will prevent static electricity from damaging the electronic components within the phone.
Ensure you wear eye protection and use caution not to cut your finger with the glass splinters.
Tips 2: Simulates testing
Screen replacement is very fragile product. We strongly suggest test before installation. Please simulates testing, which means mobile phone apart, (motherboard + LCD or screen) connected audio cable and new replacement, power on, test finished. If test OK, please install it. If it can not show, please contact us at the very first time. And please do not force it to be installed in mobile phone. We will not be responsible once the screen is installed.
The A7670E Cat-1 HAT is an LTE Cat-1 module, which supports wireless communication modes including LTE-TDD, LTE-FDD, GSM, GPRS and EDGE, with up to 10Mbps downlink rate and 5Mbps uplink rate.

The Raspberry Pi PoE+ HAT is a Power Over Ethernet (PoE+) accessory for the Raspberry Pi 3B+/4B. Compared to its predecessor Raspberry Pi PoE HAT, it features better cooling effect, implementing the 802.3af/at standard with 5V DC/4A larger power output, providing enough power for both Raspberry Pi 3B+/4B at max load and other peripherals at the same time.
By using this small HAT and some proper 802.3af/at-compliant power sourcing equipments, it is possible to provide both network connection and power supply for your Raspberry Pi in only one Ethernet cable.
The Pico-UPS-B is a dedicated UPS (Uninterruptible Power Supply) module designed for Raspberry Pi Pico. It incorporates Li-po battery switching charger with power path management, and voltage/current monitoring chip, allows monitoring the battery operating status via I2C bus.

2x user buttons and 1x reset button for easy interacting
Comes with development resources and manual (Raspberry Pi Pico C/C++ and MicroPython examples)
Advantages Of EINK
E-paper display utilizes microcapsule electrophoretic technology for displaying, the principle is: charged particles suspended in clear fluid will move to sides of microcapsule when electric field is applied, making the microcapsule become visible by reflecting ambient light, just as traditional printed paper.
E-paper display will clearly display images/texts under lamplight or natural light, requires no backlight, and features nearly up to 180 degree viewing angle. It is usually used as e-reader due to its paper-like effect.
