WIO Terminal Workbench 1

BoRRoZ · September 28, 2020, 1:31pm

Changed the power unit to LiFePO4 6000 mA followed by a DC/DC step up 3.2v to 5 v and a charger module So I can charge the device with my phone adapter.
The PMS5003 needs 5v but data lines are 3v3 so no need for level shifter when connecting to the WIO terminal.

because I have only one , I made The WIO terminal ‘clickable’ on the project box

one step closer - SERCOM UART on grove port working

WIO connected to pms 5003 reading particle sensor data

next step : CO / CO2 / TEMP and HUM sensors , a nice screen and alarm settings menu (maybe data storage on SD card / LoRaWAN connection ?)

idea : interfacing thermal receipt printer to WIO terminal
(needs external power source and bi directional level shifter)

new out of the box selftest … firmware from 2013

RPI adapters have a little higher voltage output (5.3 V) then regular phone charge adapters and that’s good for this thermal printer.

easy way to connect some diy electronics to your WIO terminal with
this cheap Proto HAT Shield Extension Board for Raspberry Pi 3

I added myself a 40 p double row 90 degrees

is it possible to decode audio with this little I2S PCM5102 DAC Decoder ?

not yet

but imagine

Nice , This looks cool

idea : handheld AirQuality analyser / data logger
waiting for the SCD30 sensor

’ This article describes four routines designed to make it easy to write games in C that use sprites on the Seeed Studio Wio Terminal. They allow you to plot erasable sprites, check sprites for collision, and move sprites on the screen while avoiding flicker. ’

WIO as a wireless LoRaWAN datamonitor

haven’t been active with LoRaWAN for a long time, lucky I saved a sensor and some gateways, put a fresh battery in it and it started working on the TTN network again

I Put it outside to check and the temp is dropping So the sensor works. Now I want that data on the WIO terminal (for fun and learning)
Because we are on COVID lockdown in the Netherlands lots of free time now to try this.

I have an MQTT broker running on my home network and I am preparing some nodes to measure airquality (indoor and outdoor) and display data on the WIO terminal when switched on.
