Page 3: Technical Details
The JN30B is designed for the production version of the Nano compute module. The version is shipped as a bare module. Auvidea can supply the mounting kit with spring and screws. Also a heat sink or a heat spreader. The 2 versions of the Nano compute modules are not pin compatible and therefore not interchangeable. ... - Page 4 The JN30B starting with rev 5 adds to extra 2 lanes CSI-2 connectors on the bottom side. The supercap add-on module is still in design. It allows to power the JN30 and Nano for a few minutes to supporters a graceful power down in case of a sudden power loss.
- Page 5 PSE48: This version is very similar to the JN30 PSE version. The difference is that it does not have the on board 12V to 48V power supply. Instead it requires a 48V DC power adapter. Advantages over PSE version:...
- Page 6 VERSION 1.4 JN30 (38346-X) By default the CSI-2 connectors are configured for 3.3V power to power cameras such as the RPi camera 2.1 with imx219 sensor or B112 module. You can find these beads on the picture below. If the beads L34 and/or L19 are populated, 3.3V is used for CSI.

Page 7: Pinout Description
3.1 and better. 48V is derived from the DC power input. The PSE48 version only with a 48V DC adapter will provide this. Pin 3 to 6 provide 10.6V power from the 10.6V onboard DC converter. Current: 1A max per pin. Able to connect Auvidea add-on boards 38363, 38372, 38385, 38391 and 38392.

- Page 14 CAM_I2C_SDA Ground Buttons There are 3 buttons on the bottom side of the JN30. These buttons are not populated with the LC version. • Button 1 (J16) - Power on • Button 2 (J18) - Force recovery • Button 3 (J20) - Reset M.2 type M 2280 (J15)
- Page 15 VERSION 1.4 JN30 (38346-X) The JN30 features an on-board micro controller (MCU: STM32F042F6P6) with 32 kByte Flash and 6kByte RAM. It monitors the power input rail and resets the Nano, if it discovers a brown out condition (voltage drop). Also it controls the UART1 bypass and the auto flashing.

Page 16: Mcu Firmware Upgrade
The C source code for the MCU is available on request (Attolic TrueStudio project). Please contact us. The MCU may be programmed with the ST/LINK programming adapter (SWCLK, SWDIO, GND). We recommend the use of the STM32VLDISCOVERY discovery kit for STM32F100 Value line. It is available in the Auvidea online shop and at digikey.com (497-10633-ND). - Page 17 VERSION 1.4 JN30 (38346-X) Appendix A TPS23861 POE PSE software control - POE controller power toggle There are a multitude of I2C commands to control the TPS23861, the registers are described in the documentation starting at page 45 (http://www.ti.com/lit/ds/symlink/tps23861.pdf) To simply toggle on and off the power on a port, in this case port 1, the following command has to...
