assembly Instructions

2 pcb versions
2.1 wrong TP4056 footprint, gnd losses
3.1 corrected some bugs
iSpindel PCB 2.1
iSpindel PCB 3.1

Assembly steps: resistances
1) Assembling resistances places on battery holder side
1 = 230Kꭥ;2 = 330ꭥor BAT43 diode; 3 = 4K7
2) Mounting of 4 x pin header
3) Attention = only for 2.1 PCB
version, wrong tp4056 footprint, it’s
need to adjust alignment between
pin header and hole of tp4056
module.
1 2 3

Assembly steps: micro slide switch
1) Solder to slide switch
Attention = only for 2.1 PCB version, please cut the pins of
the external frame of the sliding switch
2) After mounting
3) Please cut surplus pins to avoid possible short circuit
with Wemos module

Assembly steps: pin header (wemos)
1) For mounting wemos module it's not necessary to
weld all the pins, but only those interested. Prepare
the pieces 1x4 pin, 1x1 pin , 1x3 pin as picture
2) Results after mounting

Assembly steps: pin header (GY-521 – DS18B20)
1) For mounting GY-521 module, please prepare the
pieces 1x4 pin
2) Prepare dallas device , leave around 4mm pins over
pcb
2) Results after mounting

Assembly steps: 1043 keystone battery holder
TP4056 Lipo Module
1) Rotate pcb on bottom side and places the
battery holder before and tp4056 module
after

Assembly steps: GY-521 module
1) Use a female pin header as spacer, it's necessary
when the gy 521 module must be welded. This
way to ensure correct alignment with the
horizontal plane.

Assembly steps: Check GND loss (only 2.1 version)
On some pcb (not all them) I found the ground plate loss
To check with multimeter the correct continuity between BAT- and GND
(see points 1 and 2)
If it’s OPEN, its must be remove a bit solder mask until to copper plate
(see point 3) and to make a solder joint between BAT+ pin and copper
plate (see point 4)

Assembly steps: WEMOS module
1) Solder the wemos module.
2) My suggestion: install firmware before

Assembly steps: Final assembly into PetLing
1) Insert to pcb into vial.
2) Ensure that the bottom base of the pcb touch the bottom of
the vial (stop before the vial curvature and leave less 1cm)
