iot_battery_sensor v2.0

Created by Wijnand on 2018-12-11 09:25:06

2 Layer Board - 2.4932 sq in (0.9200in x 2.7100in) / 1608.51 sq/mm (23.37mm x 68.83mm)
$9.85 per set of 4 ($3.95 per sq in)

This iot_battery_sensor board v2 is intended as piggyback/hat for the iot_lora board.
(see: iot_lora_v4)

Power alternatives are: CR2032/2xAAA controlled by TPS61291, TPL5111 and/or TPS22860.
The booster (TPS22860) can be bypassed.

BOM
1 x 10uF
1 x 3,3uH
1 x TPS61291
1 x 22uF
1 x TPS22860
3 x 0.1uF
1 x TPL5111
1 x 56K
1 x 10K
2 x 4K7
2 x pin header 1x1
2 x pin header 1x2
1 x pin header 1x4
1 x pin header 2x7
1 x AAA box (€0.57)

Connections for sensors are:
GPS6MV2, (€4.15)
BME680 (€9.03)
BME280 (€2.67)
BMP280 (€0.72)
BMP180 (€0.58)
MAX44009 (€1.54)
TMP35GT9Z (€1.25)
DS18B20 (€0.80)

ATTENTION: Added to version V1.1 are connections for the sensors CCS811 and MAX44009.

ATTENTION:The new board (v.2) is tested and works fine.

2 Layer Board - 2.6680 sq in (0.9200in x 2.9000in) / 1721.29 sq/mm (23.37mm x 73.66mm)
$10.38 per set of 4 ($3.89 per sq in)

This design (a RFM95W controlled by an Arduino Pro Mini) was my first step in the world of IoT.

The board is tested with the examples of the Matthijs Kooijman
LMIC library and works perfect.

It's also used in the IoT workshop
LoraWAN Grundlagen
of the iot-usergroup.de.

A second set of PCB designs (power supply/sensor boards) are planned as piggyback/hat for this
iot_lora board. Power alternatives will be: solar cell, CR2032, 2 x AAA, supercap, TPS61291,
TPL5111 and/or TPS22860.

BOM
1 x RFM95w/868MHz
1 x Arduino Pro mini
2 x 10K (I2C pull up)
1 x SMA antenna connector
1 x pin header 2x7

ATTENTION: The update to V2.0: ADC6 and ADC7 (analog exclusively) are not connected
to JP3 anymore but PB0 and PB1 (possibility for soft serial). The HF part has now a switch to SMA
or spring antenna and added are GND planes on both sides.

ATTENTION: The update to V3.0: (on request) added a JST PH 2mm power connector
(for RAW and VCC) and a silkscreen update.

ATTENTION: The update to V4.0: added the footprint (SOP-8) for AT24CXX EEPROM to save TTN EUI's and Key's.
