Feature:  
This module is not BUCK.
Make use of imported integrated switch ultra-thin regulator module manufacturing process and synchronous rectification technology so as the conversion rate is more than 96% , what's more, calorific value is extremely low.
This module is poted by epoxy so it's waterproof, shockproof, moistureproof, anti-dust and flame retardant.
The module boasts of automatic protection function when over voltage, over current, over temperature and short circuit braking and restore normal work after the conditions.

WiFi modern ESP8266 32MB, the module is based on a wide range of exploration ESP8266 system chip from expressif. WiFi modern ESP8266 32MB, compatible with nodemcu board. We add an extra memory size of 32MB. This is better for big library projects. You do not have to worry about the size of the memory. On board there are usb-ttl serial converter ch340g, mini USB socket. DC 4 ~ 9v PowerIn pin VIN. Pitch 2.54mm (0.1 ") 15 X 2-wire pin set. Do not solder. Combine WiFi access point and feature station microcontrollers using Lua programming language is simple. WiFi Modern ESP8266 32MB, provides: arduin0 hardware IO. Can be used in the arduin0 IDE event-driven API network application 10 d0-d10, PWM function programming, IIC and SPI communication, in a board WiFi wireless network and ADC (A0, etc. can be used as an access point and / or station, host Server), connect to the Internet, get or upload data, and the developing board can use the mounting board.

2. The Function Generator component parameter table
 
3The welding installation considerations, follow these steps:
 
1. The components are welding the front board, from low to high principles, namely the first low welding components, such as, capacitor, resistor, diode, etc.
2.Welding IC socket, terminal blocks, finally power socket, adjustable potentiometer.
3.The back with a diagonal cutting pliers to cut short the pins as far as possible
 
4 Debugging steps:
 
1After completion of welding on IC, XR2206, pay attention to the direction of IC, insert the might damage the chip!
2. check the IC whether against, such as anti please timely correction.
3. Insert the power supply, power supply for 5.5 * 2.1 port, inside outside is negative polarity. For 9-12 v power supply voltage. The waveform may not be stable for more than 12 v
 
5 Using the step
 
1. J1 jumper cap plug in, SIN/TRI blue terminals output sine wave (note J1, J2 can only insert one of)
2. J2 jumper cap plug in, SIN/TRI blue terminals output triangular wave (note J1, J2 can only insert one of)
3. SQU blue terminals output pulse
4. AMP : Sine wave, triangle wave amplitude adjustment
5. FINE : Frequency fine adjustment
6. Coarse : Frequency of coarse adjustment
