NTP200 and NTP250 Hardware OverviewThe NTP200 and NTP250 feature a small form-factor measuring about 4.25" x 2.5" x 1". The front panel contains:
The back panel contains all connections:
Hardware ArchitectureThe NTP200 and NTP250 are based on a dual PCB design as shown below. The yellow top board is an embedded ARM SoC compute module and the green base board contains power supplies the GPS module and other items. A lot of value is packed into its tiny case. CPU, RAM, and StorageThe NTP200 and NTP250 use a multi-core ARM SoC from Rockchip. All NTP250's have 512MB of RAM, and most NTP200's have 256MB of RAM (in mid-summer 2021, some NTP200's shipped with 512MB due to part shortages). All boards ship with an 8GB or 16GB MicroSD card. GPS Module & AntennasIn Hardware version 14 and before, the NTP200 and NTP250 use a uBlox MAX-M8Q GPS Module. An active 3.3V powered antenna is supported. USB Admin ConsoleThe Micro-B USB connector is controlled by a WCH CH340 UART to USB adapter. This port is configured for 115200 N81 serial communication. Power Supplies and BackupThe NTP200 takes a single external DC power supply input where as the NTP250 can be powered by dual inputs (DC input and PoE). The NTP250 has hardware fail-over between the 2 inputs. Power consumption is around 1 Watt. The GPS module and RTC are powered by a rechargeable supercapacitor. If the power inputs are lost during a power outage or are temporarily disconnected. The GPS module and RTC will remain powered for about 3+ hours allowing for a quick re-acquisition of the GPS signal in just seconds instead of 30-90 minutes on a cold boot. The supercap will charge from 0% to 90% in about 20 minutes.
