Pycom is a new European company with the goal to put user friendly IoT modules with
MicroPyton on the market. The Pycom LoPy is an 868 MHz LoRa module with WiFi and BLE.
The LoPy can act as a LoRa Nano Gateway and as a multi-bearer (LoRa, WiFi and BLE)
development platform. The LoPy can be programmed with MicroPython. MicroPython uses
simple Python code, which is less complex than C, the programming language of Arduino.
With the latest Espressif ESP32 chip the LoPy offers a perfect combination of power,
flexibility and ease of use.
The new Teensy 3.5 en 3.6 are larger, faster, more powerful and more versatile
The Teensy is a small development board with many possibilities. You can create programs for the
Teensy with your own editor in C of you can use Arduino sketches. The new Teensy 3.5 and 3.6 are
larger, faster, more powerful and more versatile than the Teensy 3.2. An 120 MHz or 180 MHz ARM
Cortex-M4 with more memory, more RAM, EEPROM, micro SD card and more pins provide a lot more new
applications. The specifications of the Teensy 3.5 are slightly less than the 3.6, but the 3.5
does have a lower price.
IMU module with the latest 9DoF MEMS sensor from InvenSense
The MPU-9250 is an inertial measurement unit (IMU) with 9 degrees of freedom (DoF), where a 3-axis compass,
3-axis gyro, 3-axis accelerometer and a Digital Motion Processor (DMP) are combined on one chip of 3x3x1 mm.
Sparkfun has put the chip on a small breakout board where the I2C interface and power supply can be connected
easily. The MPU-9250 replaces the popular MPU-9150. The MPU-9250 uses less power and is more accurate. For
digitizing the chip uses 16-bit analog to digital converters (ADCs) for all 9 axes. An Arduino library is
Open source platform for Software Defined Radio (SDR)
The HackRF One Is a Software Defined Radio (SDR) instrument for sending and receiving radio signals from 1MHz to 6GHz.
It is designed to make the testing and development of modern and new radio communication technology possible. HackRF
One is an open source hardware platform that can be used as USB peripheral device or it can be programmed for
stand-alone operation. It is compatible with most SDR software like GNU Radio and SDR#. On the website of the
manufacturer Great Scott Gadgets a video course is available where the basics of DSP and SDR with the HackRF One
