5B. Assemble Stacked Version Solar Powered Weather Station

Hardware Assembly

Stacked Shield Version

Use the photos as guides. The orientation of the breakout boards and LiPo cell connections are critically important.

Use good quality small gauge rosin-core solder. Keep the iron tip clean and tinned.

Solar Charger Shield D1S-LiSo

  1. Refer to the photo. <To Be Added> Assemble the board starting with the lowest components and working up.
    1. Resistor R1
    2. Slide switch
    3. XH-2P Socket for PANEL. Observe orientation.
    4. Male header for CELL (2p). Short tails go through the board.
    5. Headers pins for TP4056 (4 x 1p). Place short tails through the board.
    6. Female sockets (2) for D1 Mini.
  2. Solder the TP4056 to the header pins (no socket). Observe the orientation of the Micro USB connector.
  3. Solder one pin of each of the 8-pin female headers (2) for the D1 Mini shield. Square them up if needed and solder the remaining points.
  4. Solder the leads from the XH-2P connector to the back of the solar panel. OBSERVE THE POLARITY: RED to +, BLACK to -.
  5. Set switch RUN.
  6. Insert the LiPo cell connector onto the CELL pins. NOTE WELL!!! OBSERVE THE POLARITY!!! Red is positive (+), black is negative (unmarked).

D1S-WX1 Sensor Shield

  1. Insert the 4-pin female header at the BME280 location. Solder one pin. Square up the header if needed and solder the remaining points.
  2. Insert the 5-pin female header at the BH1750 location. Solder one pin. Square up the header if needed and solder the remaining points.
  3. Set the BME280 on the 4-pin male header with the sensor pointing up. Solder one pin. Square up the header if needed. Solder the remaining pins.
  4. Set the BH1750 on the 5-pin male header with the sensor pointing up. Solder one pin. Square up the header if needed. Solder the remaining pins.
  5. Set the board on two males headers. Solder one pin of each on the top side of the board. Square up if needed and solder the remaining pins.
  6. Insert the BME280 and BH1750 in the sockets.

D1 Mini Assembly

  1. Place the pass-through connectors on the headers of the sensor shield to keep the connectors square.
  2. Solder the long tails of the pass-through headers (2) to the underside of the D1 Mini. Refer to the photo for the orientation of the headers.

Final Assembly

  1. Place the D1 Mini onto the charger shield so that both Mini USB connectors are on the same side.
  2. Place the sensor shield onto the D1 Mini with the BH1750 above the Mini USB connector of the D1 Mini.
  3. Set the switch on the charger board to the position opposite RUN. Connect a Micro USB cable between your computer and the D1 Mini. Upload either the IoT or IoT-APRS weather station firmware.
  4. Solder the leads from the XH-2P connector to the back of the solar panel. NOTE WELL!!! OBSERVE THE POLARITY: RED to +, BLACK to —.
  5. Insert the LiPo cell connector onto the CELL pins. NOTE WELL!!! OBSERVE THE POLARITY!!! Red is positive (+), black is negative (unmarked).
  6. Set the switch to RUN.
