The TP5100 4.2V / 8.4V Lithium Battery Charging Board is a high-efficiency charge management module designed for safely charging single-cell (1S) or dual-cell (2S) lithium-ion batteries. Powered by a switching-mode charger IC, it delivers stable, fast, and efficient charging up to 2A, making it ideal for modern electronics projects.
Unlike basic linear chargers, the TP5100 uses a high-frequency DC-DC architecture, reducing heat generation and improving efficiency—especially useful when charging from higher input voltages.
This module supports the complete lithium battery charging cycle, including pre-charge, constant-current (CC), and constant-voltage (CV) stages, ensuring battery longevity and safety. On-board indicator LEDs provide clear charging and full-charge status.

TP4056 1A 3.7-4.2V Lipo Battery Charging Module with current protection-Micro USB
Sensors, Modules & ShieldsTP4056 1A 3.7-4.2V Lipo Battery Charging Module with current protection-Micro USB
This tiny module is perfect for charging single cell 3.7V 1 Ah or higher LiPo cells such as 16550s that do not have their own protection circuit. Based around the TP4056 charger IC and DW01 Deep Drain Battery Protection IC this module offers 1A charge current. The module cuts off charging current when finished.
Furthermore, when the battery voltage drops below 2.4V the protection IC will switch the load off to protect the cell from running at too low of a voltage – and also protects against over-voltage and reverse polarity connection (it will usually destroy itself instead of the battery) however please check you have it connected correctly the first time.

DHT22 temperature-humidity sensor
The DHT22 temperature-humidity sensor is an ultra-low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed). It is fairly straightforward to use but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old

ADS1115 ADC – 4 Channel
ADS1115 ADC – 4 Channel For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-ended input channels or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and it is super easy to use. It is a great general-purpose 16-bit converter.
