The ESP82 is the impressive follow-up to the popular ESP8266 WiFi chip
The SparkFun ESP32 Thing is a comprehensive development platform for Espressif's ESP32, their super-charged
version of the popular ESP8266. Like the 8266, the ESP32 is a microcontroller with WiFi, but also has Bluetooth
LE and naerly 30 I/O pins. You can program with the Arduino IDE after installing the ESP32 Arduino Core. In
addition to the WiFi/BLE SoC the Thing has an FTDI FT231x, which converts USB to serial allowing your computer
to program and communicate with the microcontroller. The Thing also features a charger for a Lipo battery
Wireless IoT over great distance with LoRa for the Raspberry Pi
LoRa is a wireless technology for sending and receiving a small amount of data over a great
distance using little power. The Dragino LoRa/GPS HAT is an expansion module for the Raspberry
Pi. For LoRa the RFM95W from HopeRF is used. The Quectel L80 is an advanced GPS with AlwaysLocate™
technology allowing the HAT to fix position quickly, even at indoor signal levels. On the website
of the manufacturer, you can find several examples, like setting up a Lora Gateway, how to get
temperature data via Lora and getting GPS to work.
This laser sensor from Garmin measures distance up to 40 meters accurately
The LIDAR-Lite v3 is a compact, powerful, optical sensor from Garmin for accurate
measurement of distances up to 40 meters. This laser-based sensor is easy to use
and has all the features which made the predecessor LIDAR-Lite v2 so popular. For
example you can optimize accuracy, range and measurement time for your application.
LIDAR-Lite v3 has an accuracy of +/- 2.5cm at a distance of more than a meter. The
repetition rate is 1-500Hz, the power supply 5V and the interface is 12C or PWM.
For the LIDAR-Lite v3 an Arduino library is available.
With the J-Trace PRO you will find (almost) all bugs in your embedded system. This debugger
for ARM Cortex-M offers a real-time continuous streaming trace via its Gigabit Ethernet interface.
There are no longer any limitations by internal buffers or slow data transmission. J-Trace PRO can
capture data over a long period of time, enabling you to find bugs that sometimes occur. To allow
you to get acquainted to streaming trace, the J-Trace PRO is now supplied with the M trace reference
board. The corresponding tutorial can be found on the website of the manufacturer Segger.
