iot_lora_v4.2
Created by Wijnand on 2019-10-09 11:08:582 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.
ATTENTION: The update to V4.2: added footprints for 2 x IPEX-Connector and extra debug LED (D1) on 10.

Autolight-board

Auto light
Attiny10 & APDS-9930 based automatic light/switch
https://github.com/N-Storm/autolight
https://easyeda.com/NStorm/autolight-board
This project utilizes small ATtiny10 mcu to work with APDS-9930 ambient light (AL) and proximity I2C sensor.
This is used for automatic "smart" light in a drawer. Once the drawer are open the APDS-9930 will notice proximity change
and trigger a preset interrupt and MCU will come from sleep to check if AL level are below set (i.e. it's dark around).
If the set condition for AL level will be met, it will enable HIGH level on PB3 pin. Which is connected to a MOSFET or any other switch to enable LED light.
Reset shares same PB3 pin so it must be disabled via fuses. You will have to apply +12V to PB3/RESET pin to reprogram attiny10 after flashing RSTDISBL fuse.
The PB2 port are used as INT0 for sensor interrupts to wake MCU from sleep on proximity change event.
Building
Fetch the latest trunk:
git clone https://github.com/N-Storm/autolight && cd autolight
Then tweak some settings in autolight.h if required. They are commented. After that do a:
make && make flash && make fuse.
:warning: After you do a make fuse step, you won’t be able to program MCU again without applying +12V to RESET pin (make sure it’s not connected to your programmer hardware :warning:
Alternatively you can use pre-built binaries with the default settings from releases section.
Connecting
PB0 ↔ SCL
PB1 ↔ SDA
PB2 ↔ INT
PB3 are the module digital output, with logic LOW when light should be turned off and HIGH when it should be on. Suited for connecting to an N-channel FET driving the LED light.
Please be aware that the APDS-9930 module requires 2.5 – 3.6 V for it’s operation on Vdd+Vbatt (IR LED power). I recommend to use a 3.3V LDO for powering both MCU & APDS-9930.
Schematics & board are available on EasyEDA: https://easyeda.com/NStorm/autolight-board
:warning: This board has two places for LDOs - U3 & U4. Solder only one of them! :warning:
They replace each other. The board are made so they could replace each other. Alternatively edit board/schematics to replace them with your favorite LDO.
This project utilizes software I2C library by eXtreme Electronics, India.

MySensors - DS18B20 temperature sensor
Created by serisman on 2019-04-30 05:56:232 Layer Board - 0.1971 sq in (0.4670in x 0.4220in) / 127.16 sq/mm (11.86mm x 10.72mm)
$0.79 per set of 4 ($4.00 per sq in)
This is a bare minimum DS18B20 based temperature sensor node.
It is intended to be as small as possible, with really long battery life. The ATmega328P is powered directly from the battery, but the nRF24L01+ and DS18B20(s) are powered through an efficient XC6206 3.3v LDO regulator (U2). The battery can be 3x AA/AAA, or a LiPo/Li-ion cell (i.e. 18650).
This uses the SMD version of the nRF24L01+ module.
All resistors/capacitors are 0805 sized with the following values:
- R1 - 4.7kOhm
- C1,C2 - 4.7uF - 10uF
- C3,C4 - 100nF
The ATmega328P MCU needs to be programmed before being soldered, so the MYSBootloader is recommended.
