Controller r2.1 Assembly Instructions

Following a simple sequence of steps, you can have a fully assembled device in approximately 40-60 minutes. You will need the following tools and materials:

• multimeter
• soldering iron
• solder
• soldering paste/rosin
• wire cutters/diagonal pliers
• isopropyl alcohol for cleaning the board after soldering
• small brush (e.g., toothbrush) for cleaning the board after soldering
• it is convenient to have a "third hand" or vise

Before assembly, you must set the output voltage to 5.1V on the MP1584 converter and resolder the frequency selection resistor on the hx711

Assembly Sequence

Header Pins

In the current assembly variant, header pins of 4 and 5 pins respectively are soldered to the board for connecting the display and encoder. For connection, use wires terminated on one side with BLS connectors (Dupont/black) which are soldered into the encoder and display; if necessary, the header pin installed at the factory can be desoldered from the encoder.

The BME280 sensor is soldered to the wires included in the kit; the wire into the sensor connector (white) into the board
