MakerFocus Raspberry Pi 4 Battery Pack UPS, RPI Pack Standard 10000mAh Raspberry Pi Battery USB Pack Raspberry Pi Latest Version V3Plus Expansion Board Power Supply Type-C for RPI 4B 3B+ 3B 2B+

...Indicates that there is no voltage at the output. 3) Charge charging indicator LED: When the UPS is externally charged via the TYPE-C USB interface, the Charge LED starts to work.
The UPS has overcharge and overcurrent protection functions: When the UPS externally outputs about 4A, the UPS will consider the external circuit to be in a short-circuit state and automatically cut off the output. The lithium battery board that comes with the UPS has an overcharge and overdischarge protection board. Prevents the battery from being overcharged and overdischarged when the external circuit is abnormal, thereby reducing the possibility of damage to the battery..
Two output modes: In addition to the regular output via the USB port, the V3P output interface adds an LC filter, the ripple is about 20mV under no-load condition, and the ripple is about 50mV when a Pi4 is connected.

AITRIP Pro Micro ATmega32U4 5V/16MHz Module Board, Replace with ATmega328 Pro Mini Compatible with Arduino with 2 Row pin Header 10pack

ATmega32U4 microcontroller: The Pro Micro is similar to the Pro Mini except with an ATmega32U4 on board. The USB transceiver inside the 32U4 allows us to add USB connectivity on-board and do away with bulky external USB interface..
The acceptable voltage range is 5 to 9 V..
On-Board micro-USB connector for programming.
This tiny little board does all of the neat-o tricks that you're familiar with: 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorite pro-compatible boards but this little guy can go just about anywhere. If you're supplying unregulated power to the board, be sure to connect to the "RAW" pin on not VCC..
This latest revision corrects the silk error from the last version of the board so that pin 14 is correctly labeled. We've also added a PTC fuse and diode protection to the power circuit and corrected the RX and TX LED circuit..
