Why the LCD doesn't work with my Raspbian To use the LCD with the Raspberry Pi official image, driver should be installed first. Please refer to the user manual. However, for the first testing, you may want to use our provided image directly. Why the LCD still doesn't work with the Waveshare provided image?Make sure the hardware connection is correct and connects fine. Make sure the image in TF card is burnt correctly.The PWR will keep on and the ACT will keep blinking when the Raspberry Pi starts up successfully, in case both of the two LEDs keep on, it is possible that the image was burnt incorrectly OR the TF card was in bad contact. Which power supply should I use?It is strongly recommended to use a stand-alone 5V/2A power adapter, because the PC's USB port might have not enough power to support the Pi and LCD.

Nowadays Li-ion batteries are most popular to be used in many indoor and outdoor gadgets, these batteries are preferred due to their high charge storage capacity. Such batteries are widely used in today’s portable devices. they are compact, more efficient and have a high energy intensity compared to other types of batteries. One drawback of such a battery is that we need to continually monitor their charging and discharging process if we do not do this, it badly affects battery life and also reduces the charge storing capacity. If we discharge such battery below certain voltage range, then the battery cell has a high risk of damage and if we overcharge such battery then it may explode. To overcome such issues, we can use battery protection and battery charging circuits such as this product. This is Li-ion single-cell charger/protection circuit which can be used to charge a single cell of 15 Amp capacity or 2500Mah parallel-connected 5 to 6 li-ion cells. In this MOSFET are employed to do the monitoring task which protects our battery cells from overcharge, over-discharge, and from short circuit.
