    Teensy 4.1 Beta Test

    Has anyone from Europe already received the beta board (except the pre beta tester)? Mine has been in Belgium for a week now and is not moving anymore. I think I will order a Teensy 4.1 from sparkfun, with shipping by Fedex or UPS - no USPS this time.

    How to connect Teensy 3.2 with Rx TGY-IA6C for flight simulator

    It's what I would expect. In front of the voltage regulator is a diode which adds an additional voltage drop (about 300 mV).

    Is this teensy3.2 ref schematic correct ?

    I tried to explain why a second schematic exits, which is a little different. So... the board itself is not outdated. For the github repos, the one with the eagle files is up to date - the one with the kicad files i don't know. But i think both should be good (except the wrong 0.1 uF capacitor...

    Teensy 3.6 whit 74hc595 - Pinout and power

    I think 74HC595 is the wrong chip for this application. It has to do with the minimum input high voltage for 74HC595 pins. The minimum input voltage is calculated with 0.7 * Vcc. With 5V supply, the input voltage should be > 3.5V but the max output from a Teensy 3.6 is 3.3V. 74HCT595...

    Pin count discrepancy.

    The MK66FX1M0VLQ18 is split into two symbols. The first symbol contains pin 1 - 72 and the second symbol pin 73 - 144. In Ultra Librarian one can switch between the symbols with the "View Previous" and "View Next" buttons.

    Legacy Libraries

    Legacy is the old Arduino-1.0 library structure. Arduino 1.5 introduced a new extended library structure: https://github.com/arduino/Arduino/wiki/Arduino-IDE-1.5:-Library-specification There is no problem with Legacy libraries. But perhaps the support will be dropped at some point in the future.

    Question on digitalWrite, on SPI bus (T3.5)

    Can you measure the voltage in high state? I think there is an internal leakage path to VDD in the mcu and you can't pull the pin voltage higher than ~4V.

    Question on digitalWrite, on SPI bus (T3.5)

    Teensy 3.5 & 3.6 Schematic Posted

    I think this is the wrong fuse type. It's a "one shot", non-resettable fuse which must be replaced once it has been activated (blown). The fuse used on Teensy is a resettable PTC/PPTC. Not confirmed, but I think it is Bourns MF-FSMF050X.

    Teensy 3.2 + Adafruit NXP Precision 9DoF Breakout + Teensy Fusion Library?

    The FXOS8700 accel has two inputs for I2C address selection. Prop shield sets them to GND and the Adafruit board to Vcc. So, on the Prop shield the I2C address is 0x1E and on the Adafruit it is 0x1F. You need to change the I2C address in the NXPMotionSense library. Same for the gyro.
