This section describes the Pinnacle™100 development board hardware. The Pinnacle™100 development board is delivered
with the Pinnacle™100 series modem loaded with Zephyr Out of Box (OOB) example code.
The Pinnacle™100 development board is a universal development tool that highlights the capabilities of the Pinnacle™100
modem. The development kit is supplied in a default configuration which should be suitable for multiple experimentation
options. It also offers several header connectors that help isolate on-board sensors and UART from the Pinnacle™100
modem to create different configurations. This allows you to test different operating scenarios.
The board allows the Pinnacle™100 series modem to physically connect to a PC via the supplied USB cable for development
purposes. The development board provides USB-to-Virtual COM port conversion through a FTDI chip –part number FT232R.
Any Windows PC (XP or later) should auto-install the necessary drivers; if your PC cannot locate the drivers, you can
download them from http://www.ftdichip.com/Drivers/VCP.htm
The Pinnacle™ 100 development board has the following features:
▪M.2, KEY E, PCI connector to connect a Pinnacle™100 series modem into the development board

▪JLINK USB port, J18, micro-B connector –If it requires the SWD to USB path*
▪HL7800 USB port, J7, micro-B connector –If it requires the HL7800 to USB path**
▪NRF USB port, J10, micro-B connector –If it requires the NRF to USB (Pinnacle™ 100) path
▪An external DC supply (4.4V-12V), connected to either the DC Plug, J17, or the Bench connector, J6
▪4 x AA batteries –Four AA Energizer Lithium (4.4-7.2V) batteries connected to terminal block, J22
▪2 x AA batteries –Two AA Energizer Lithium (2.2-3.6V) batteries connected to terminal block, J2
Note: * –Connect USB cables to both J18 and J30
** –Connect USB cables to both J7 and J10
Recommend using a 1A or above for USB port connections
VIN_ADC is intended for 2AA or 4AA battery measurement and is not intended for ext DC voltages above 7.2V.
The power sources are first selected by setting SW7 (Source Select switch) to the desired power option (includes USB,
external DC supply, 4AA batteries, and 2AA batteries). The selected power option is then fed into SW6, which is the ON/OFF
switch for the DVK. For all power option, except 2AA, the output of SW6 is fed into a Buck-Boost regulator that feeds both a
1.8V and 3.3V linear regulator. The output of the Buck-Boost Regulator is also fed to the PinnacleTM 100 modem VIN pins
through J4 which allows for modem current measurements.
The Power supply circuit uses load switches to isolate nets from each other, this allows the Buck-Boost Regulator to be
bypassed when connecting 2AA batteries and to directly power the modem, the 1.8V regulator is enabled for IO support.

The development board provides two options for connecting to the modem’s SWD interface, the signals SWDIO, SWDCLK,
and SWO, are switched by U10 based on the position on SW13 DEBUG SELECT:
▪External header (J14) allows an external SWD debugger/programmer to be connected to the modem. The DEBUG
SELECT (SW13) must be set to EXTERNAL.
▪The internal SWD circuitry can also be connected to the modem. The DEBUG SELECT must be set to INTERNAL. The
ATMEL SUPPLY switch, SW13, must be set to ON. USB cables must be plugged into J18 (JLINK) and J30 (FTDI),
shown in Figure 13.

Note: We recommend that you use SWD (two-wire interface) to handle future Pinnacle™100 modem firmware upgrades.
You MUST wire out the SWD (two-wire interface) on your host design (Four lines required: SWDIO [1.8V Logic],
SWDCLK [1.8V Logic], GND, and VIN (2.2-5.5)].
M2.60 (P1.00) can be used as SWO (Serial Wire Output) and is not necessary for programming Pinnacle™100 over the SWD
interface.
M2.73, nReset_BLE, is not necessary for programming Pinnacle™100 over the SWD interface.
The NRF has a direct USB connection, J10 (NRF USB). The HL7800 also has a direct USB connection, J7 (HL7800 USB).
Figure 14, shows both USB connectors and J10 must be connected when using J7, to provide 5V to the modem pin M2.9.

Note: The PinnacleTM 100 connections to the buttons can be removed by switching the positions of the DIP switches –S4
Position 1 (SW1), S1 Position 6 (SW2), S3 Position 6 (SW3), and S1 Position 5 (SW4) –to the OFF position.
SW1 is used by the bootloader to enter UART mode, so that must be considered if a user wants to use it for another
purpose.

The VIN to the modem can be sampled by enabling (1.8V logic) modem pin M2.55 (P0.28), VIN_ADC_EN and then taking
ADC measurements using modem pin M2.53 (P0.29), shown in Figure 23.
Figure 23: VIN monitor schematic
The DVK includes a GPS antenna shown in Figure 24,that is connected to the modem using J23 and a U.FL to U.FL cable.

Figure 25 shows a removable jumper (on J4) which is provided to break the power supply line directly to the modem, allowing
the measurement of the PinnacleTM 100 current consumption.
For normal operation, the jumper on J4 must be fitted (and is fitted by default).
