Board specifically made for NT and TSTorM32 setups, with on-board motor drivers.
Boards specifically made for NT and TSTorM32 setups.
General purpose version.
Hat for the Raspberry Pi.
Series of stackable boards with 20x20 mm hole pattern: Main board, NT Motor-Encoder module, NT Triple Motor module, NT Logger module.
changes in v3.3:
- board specifically designed for NT and T-STorM32
- no motor drivers on board
- 3 NT plugs to make it easy to connect several NT modules
- NT-X plug carrying also the battery voltage
- 5 V power rail on the NT bus, with sufficient "juice"
- Rx&Tx on NT bus swapped, to avoid cable crossing to connect with NT modules
- support of stacking with a "high-power" extension board
- MPU9250 on board, spi (no i2c anymore!)
- firmware update procedure via USB
- ESP8266 port for WIFI connectability
- CAN bus port
- no BOOT0 button, smaller RESET button
- 0402 size parts
- board size as small as I could get it with a 2 layer design: 40 x 25 mm
- mounting holes, 3 mm diameter, 35 mm apart
changes in v1.3:
- voltage regulator in DPak package
- AUX2 instead of 3.3V pin at AUX port
- solder jumper to disconnect bluetooth led
- values of resistors R12,R13,R22 changed
changes in v1.2:
- minor issues of v1.1 corrected
- Futaba S-bus support
- Spektrum sattelite connector
- usb disconnect network modified to suite F4 processors (thanks ala42!)
- usb voltage protection diode added (as in v0.17)
- further minor changes in scheme and layout
changes in v1.1:
- reverse voltage protection added
- layout supports TC4452 motor drivers in DFN package for increased power capabilities
- high-side pnp open collector output for driving an IR led added
- additional connector for I2C#2 port added
- larger solder holes and pads for battery power connection
- improved pin arrangement for easier use
