PCB
Wemos D1 Mini
• Keep the main board
• Keep 2x 8 way board
headers
• Throw away the bottom 4
board sockets
Prep: Accelerometer
• The accelerometer comes with:
• GY521 Board
• 8 way straight header
• 8 way 90 degree angled header
• Cut the 8 way angles header
down to 4 way and solder as
shown
• Snip off the excess header
section as shown
• Keep the straight 8 way for the
LiPo Charger
Prep: LiPo Charger
• Cut the 8 way header from
the accelerometer into 6 off
1 way and 1 off 2 way, set
the 2 way aside for later
• Solder the 6 off 1 ways as
shown
Prep: Wemos D1 Mini
• Solder the 2x 8 way board
headers as shown
• Program the board now,
before it is soldered
Prep: Battery holder
• Snip the inside halves of the
battery clips
The Build: Quick Warning
• Care must be taken during the build so as not to foul the
battery when fitted in the holder, if the leads pierce the
battery you risk a lithium fire
• Ensure all joints are as flush as possible in the RED area,
cut all legs flush to the board before soldering.
The Build: 1: Accelerometer
• Fit the prepped
accelerometer as shown
• Before soldering cut all legs
flush to the PCB
The Build: 2: Passives
• Fit the 220k resistor
• Fit the 4k7 resistor
• Fit the BAS43 diode (take
care that it is the correct
way around)
The Build: 3: Switch and Reset Header
• Fit the Switch
• Fit the 2 way
header left over
from the
accelerometer
The Build: 4: LiPo Charger
• Fit prepped LiPo
charger
• Once fitted trim the
pins down to
prevent the shorting
to the Wemos D1
Mini
The Build: 5: Wemos D1 Mini
• Fit the prepped and
programmed Wemos D1 Mini
• Don’t skip the programming
before soldering it down, it
USB connector gets difficult to
get to
The Build: 5: Temperature Sensor
• Fit the DS18B20 temp. sensor
• Before soldering cut all legs
flush to the PCB
The Build: 6: Battery Holder
• Ensure all the solder joints on the
board under the battery holder
are as flush as they can be
• Fit the prepped battery holder
The Build: Complete
