WZP-PT100 PT100 Thermal Resistance Platinum Temperature Sensor Probe

This Platinum thermal resistance probe is an accurate, sensitive, and stable temperature sensor with a large operating temperature range. The sensor has a stainless steal cased ceramic body which contains a small platinum thermal resistance wire allowing for temperatures to be measured between -200 and 420oC. The WZP serial has a small structure, wide range, good reliability, and short thermal response time. PTR sensors opperate by varying there resistance as a function of temperature with a close to linear relationship and minimal deviation. With low self heating the probe allows for a maximum of 5mA current resulting in a rise of not more than 0.3oC

Temperature gradient (0oC to 100oC): 0.385 Ohms/oC
Approx probe size: 30mm length x 4mm diameter
Approx cable length: 500mm

4 Route 4 Channel MOSFET Button IRF540 V4.0 Module

4-channel MOSFET switch. It can supply up to four groups of electronic switches to control different circuit blocks respectively. Limited by the working priciples, MOSFET can only be used to control the DC circuit, such as DC-LED screen and so on, but not suitable for AC circuit control. 

In some extreme cases,It can be used to control 100V/33A DC circuit. However, it is suggested that the controlled DC voltage is more than 9V.

Just an experiment, we pick up two LED belts to test this module

Test code is as below : 


int s1Pin = 6;

int s2Pin = 7;

void setup() {

  pinMode(s1Pin, OUTPUT);

  pinMode(s2Pin, OUTPUT);



void loop() {

  int i;


  digitalWrite(s1Pin, HIGH);

  digitalWrite(s2Pin, HIGH);



  digitalWrite(s1Pin, LOW);

  digitalWrite(s2Pin, LOW);



  for (i = 0; i < 10; i ++) {

    digitalWrite(s1Pin, HIGH);


    digitalWrite(s1Pin, LOW);




  for (i = 0; i < 100; i ++) {

    digitalWrite(s2Pin, HIGH);


    digitalWrite(s2Pin, LOW);

HobbyKing FPV250 Racer Long Frame Upgrade kit

This is the perfect upgrade to the wildly popular FPV250 Quadcopter, allowing more space and configuration options for FPV use.

The Long Frame kit is precision CNC cut and matched with hot red anodized aluminum standoffs. The upgrade kit is a direct bolt on no fuss option part and has a few intuitive features. The FPVpan and tilt system is still fully accessible with the servo slot considered as well as a new forward looking FPV camera mount between the frames. The flight controller bay is still fully accessible making any type of layout headache free. One possible option is to flip the Long Frame kit and have it hang from the bottom for a sleek low profile obstacle hugging machine.

*Note: This is the upgrade long frame kit and does not include the required FPV250 frame.
