TP4056 Module Lithium Battery Charger with Protection Micro USB

Velostat or Linqstat film of pressure sensitive material ideal for DIY projects on Arduino, Raspberry or other platforms. When folded or creased it reduces its resistance allowing for flexible sensors.

The ideal tin for application in consumer electronics circuits. 17g of 0.8mm diameter tin wire. Consists of 60% tin, 40% lead. In a handy pen dispenser format.

The 19.5cm antenna can be connected to the ESP8266 module with ipex. It works on LoRa 433/868/915 MHz frequencies with SMA interface.

Definition of the Hall effect: When a current passes through a bar of semiconductor (or conductive) material, and if an induction magnetic field B is applied perpendicularly to the direction of current flow, a voltage, called the Hall voltage, proportional to the magnetic field, and the current appears on the side faces of the bar.
This voltage is proportional to the speed of movement of the charge carriers, It is considerably higher in semiconductor materials than in metal conductors. Magnetic Sensor Characteristic: - Input Voltage: 3.8-30VDC - Output current: 40mA
High output current capacity -40 mA maximum absolute
Quad-Hall design virtually eliminates static mechanical effects
Magnetic compensated temperature - Digital current sinking output

Characteristic: -Length: 20cm
-Quantity: 40 cables
-Mono Dupont connectors on both ends
-Compatible with 2.54mm female connectors
-High quality and good working condition
-Easy to install and use
