What is it? This project is about an SMD Reflow & filament joiner controller. For SMD use the Auto Mode and for the filament joiner use the manual mode in the controller. The controller features an Arduino mini with an OLED 128 x32 display and also a rotary encoder to navigate through the menus.
This controller has two modes :
Auto mode SMD Profile -- Indication of current step (soak, reflow, cooling)
-- Timer for every step
-- Target temperature and time are adjustable on the fly
Manual control of hot plate Setup Mode Has a setup mode where parameters can be adjusted
Soak temperature (preheating)
Soak time (preheating)
The target temperature for Manual mode
Designed to drive small hotplates 48W and also can be used with an SSR to drive bigger hot plates!
Uses standard 100k 3950 NTC sensor.
Why did you make it? I have gone through many designs and they were all big and bulky and always found a problem to install them in an oven or near a hot plate. This version solves this issue as the board is very small and can be easily fitted.
What makes it special? The controller can also accept these sensors for temperature reading. By default, it is shipped with the NTC sensor configured. Kindly send me a message to upload the firmware according to the sensor board to be used.
MAX66750 - Use an external board: Not Supplied
MAX31850 - Use an external board: Not Supplied
NTC 3950 SENSOR - Default Sensor : installed on board.
Has these output ports
Heater control - heater 12v 48w output mosfet driven. Fan control - drives 12v fan Buzzer control - drives a buzzer Led Indication when the heater is on Reset switch to reset controller Specifications Input Voltage : 9 - 12v Heater Output : 9 - 12v Heater Power : 48W
I have provided Product options for those who wish to use an external board. The controller will be supplied to support the external board sensor.
If the option External sensor is selected, the external board is not included and you need to buy it separately. only the controller with the code will be supplied.
What is Included:
1 x Assembled and Tested Controller 1 x Printed User Manual.
