nRF24L01+ 2.4 GHz radio add-on board for Teensy 3.1 with smaller 16 MHz crystal and in-board antenna instead of low-range ceramic antenna

Breakout board for ST Microelectronics' VL6180X proximity sensor for breadboarding with Teensy and Arduino. VIN is between 3 and 5.5 V. Sensor uses laser range finding (!) to detect absolute distances independent of surface reflectance up to 10 cm away or more depending on ambient lighting. Can be used to recognize hand gestures for sophisticated touchless micro-controlling. Small package, low cost, and low power usage makes integrating into existing projects, or use as a Teensy 3.1 or Arduino Pro Mini add-on board very attractive. Does it work as advertised?

MAX21100 6-axis gyro/accelerometer motion sensor plus LIS3MDL 3-axis magnetometer plus MS5637 24-bit pressure sensor. This board can be a Mini Add-On shield for Teensy 3.1 or a standalone breakout board for Arduino breadboard use. Solder jumpers on the back change the source of power to make it breadboard friendly. The board is hardwired for I2C since the pressure sensor is I2C only. The MAX21100 reads data from the magnetometer slave as an I2C master and performs 9 DoF sensor fusion in hardware with quaternions or AHRS heading as output by direct register read. This is what the Invensense MPU9250 DMP should have been; maybe Maxim Integrated got it right?
