2 Product Overview
The Swarm Tile (Model: TILE01) satellite data modem transmits and receives data to and from
Swarm’s space network and is designed to be embedded into a third-party product. Swarm
backend systems support the delivery of customer data via a REST API to the cloud service of
each user’s choice.
The Tile is a module suitable for a variety of low-bandwidth use cases: from connecting people
and tracking vehicles, ships, or packages to relaying sensor data for agriculture, energy, and
industrial IoT applications.
Tile is a Surface Mount Technology (SMT) module that can be easily integrated into any new or
existing PCB design. The Tile communicates via a standard 3.3V CMOS serial UART interface
or a PC interface with a USB-to-serial converter.

4 Electrical Interfaces
The following subsections contain information for the electrical interfaces of the Tile.
4.1 User Host Device
The user host device provides the following connections to the Tile:
● DC power supply input: 3.3V, 1000 mA peak
● Serial data interface
● Satellite signal (Use either the provided U.FL connector labeled SAT or Pin 18. See
section 5.3 - RF Trace Layout Design for more information)
● GPS signal (Use either the provided U.FL connector labeled GPS or Pin 8)
● GPIO_1 (optional)
4.2 Tile Pin Allocation
The pin numbering scheme of the Tile is shown in Figure 4. The module pins allow soldering
onto a printed circuit board (PCB) using standard reflow soldering techniques. The pin function
assignment is given in Tables 6 and 7. Multiple supply grounds are provided and all supply and
supply grounds are required to be connected to the power supply in order to limit the current on
any one pin. Multiple signal grounds are provided to reduce cross-talk. Pins 13 and 14 are
intentionally left empty, and must be left unconnected.

Connection is unbuffered directly to a GPIO on the Tile processor.
Configuration will be provided via Tile firmware. GPIO pin is 3.3V tolerant and
open drain, with a sink current limit of 8 mA (20 mA with a relaxed VOL/VOH)
8
GPS_RF uses 50 Ohm input impedance. Pin 8 by default is not connected - by
default the GPS U.FL connector is selected. To enable Pin 8 the resistor R5
(adjacent to GPS U.FL connector) must have a 0-ohm resistor (0402) placed
and a 50 ohm strip line to the RF connector.
9, 10
The 3.3V connection points are in parallel with one another and power the Tile.
If the designer wants to enable a complete power off mode, a load switch can
be provided here.
18
SAT_RF uses 50 Ohm input impedance. Use of SAT_RF instead of the SAT
U.FL connector requires the user to use the FCC certified layout as defined in
section 5.3 - RF Trace Layout Design

4.3 DC Power Interface
The DC power interface consists of the DC power inputs as summarized in Table 8. The power
requirements apply to DC power measured at the Tile user connector input and not at the output
of the power supply. It is required that users incorporate the required bypass capacitors for the
supplied power input as can be seen in Figure 5.

GPS acquisition mode for approximately 30 seconds after exiting from sleep mode, on powerup,
or when the Tile needs to re-acquire a GPS fix (approximately once every 3 hours) while the Tile
is continuously powered on and not in sleep mode.
