Arduino and 3D printer accessories include lots of kinds. At this article, I wanna share you something about module board, 3D printer accessories, and smart robot accessories. If you are interested in them, you could have a look! 1. 12v thermostat Specification: Supply voltage: DC 12V Static current: ≤35MA, attract current ≤65MA Output voltage: DC 12V Output power: 10A relay Measurement input: NTC (10K 0.5%) Waterproof Sensor Environmental requirements: -10 ~ 60℃, Humidity 20% ~ 85% Dimensions: 48 x 40mm Cable length: About 52 cm Temperature control mode: ON / OFF Temperature range: -50 ~ +110°C Control accuracy: 0.1°C Hysteresis accuracy: 0.1°C Refresh rate: 0.5S High temperature protection: 0 ~ 110°C Resolution: When temperature is 0.1°C, the resolution is -9.9~99.9, other temperature segment is 1°C 
It is sold at a price of $ 3.69. 2. 12v delay timer Users can display the buttons and select the following nine kinds of functions in one, you can set and save 9 kinds of function parameters, you can also view the current function parameters, time parameter sets the minimum one second adjustable accuracy of better than 0.1 seconds. 
Cheap price it is that only be sold at a price of $ 7.34. 3. 10w solar battery charger Feature: Product Model: ICO-SPC-10W Specifications: 10 watts / 18 volts (for 12-volt system) (9-10W) Test under standard conditions (temperature is 25 degrees, AM1.5, 1000w/m2) Size: 350 x 245 x 17 mm (aluminum alloy frame, four mounting holes) Peak voltage: 17.9 volts Peak current: 0.56 Ann Open circuit voltage: 22.41 volts Short circuit current: 0.62 Ann Power deviation: ± 5% Net Weight: about 0.8 kg Junction Box Type: without diode without wires 
This one is only sold at a price of $ 28.39. 4. 0.5mm drill bit Large chip removal space: Small chip resistance, smooth chip removal, drilling heat is small, can reduce drilling contaminated. Extraordinary cutting edge sharpness: As a result of nanotechnology and advanced grinding technology, the drill cutting edge is sharper than before, can reduce the cutting forces and reduce broken drill rate, improve the hole wall quality. Based clients application design tool: Drill bit rich varieties to meet different application requirements. All the parameters of the drill bit, such as drill core thickness, core of drilling taper, etc., are carefully designed, effectiveness significantly; Symmetrical cutting edge: In favor of efficient cutting, avoid offset drilling. Processing range: PCB, SMT, CNC, mould, plastic, copper, stainless steel and other precision metal parts processing. 
It is only sold at a price of $ 5.45.
