panStamp shield kit for RaspberryPI Maximize

panStamp shield kit for RaspberryPI

This shield is the natural gateway between a Raspberry PI computer and any panStamp network. The kit provides a RTC chip (DS1338) with battery backup for the RPi, keeping the clock time in case of power outage or lack of Internet connectivity

The new Raspberry PI 3 has introduced some instabilities in /dev/ttyS0 as the serial port available from the GPIO connector. It's advised then to use this shield only with Raspberry 1 and 2 for the moment until a new version of raspbian fixes this issues.

Our shield for RaspberryPI is the most elegant way to add low-power wireless connectivity to the most popular compact computer in the world.

Featuring a panStamp, this shield releases the computer from having to deal with the low-power wireless communications. Instead, the on-board panStamp acts as a modem connected to the RPI UART (serial port).
This shield also includes a real time IC with battery backup so that we no longer depend on remote NTP servers and Internet connections to get the current time, even after an outage.


  • panStamp managing all the low-power wireless communications on the free 868/915MHz ISM bands.
  • SMA connector for external antenna
  • DS1338 IC for the RTC function with battery (CR2032) backup.
  • Size: 44 x 34 mm


This shield includes a real time IC (Maxim DS1338) with battery backup so that we no longer depend on remote NTP servers and Internet connections to get the current time, even after a power outage.

This shield does not include a panStamp or SMA connector. Take a look at the following pictures before assembling the wireless module and connectors to the shield board.

Assembled RPi shield

The whole has a low profile, so you can use this shield with most enclosures for Raspberry PI.

You can also solder a wire antenna instead of a SMA connector. The SMA connectivity in the above picture is shown only as a reference. 


Raspbian comes with the UART pre-configured to be used as a serial terminal. In order to use the UART with our shield, we need to free the on-board serial port as shown in this tutorial

Enabling the RTC function also implies doing some changes on Linux. There are many tutorials about this in the net but this is our preferred one. Raspbian has the I2C interface blacklisted. Before running through the above guide, be sure you enable I2C. To do this, edit the file '/etc/modprobe.d/raspi-blacklist.conf' and comment out the line 'blacklist i2c-bcm2708'.
After running through the hwclock guide, run 'sudo update-rc.d enable' to enable the hwclock at boot. Now, run 'sudo service ntp restart' to persuade ntp to update the local time. The last step is to write this time to the hwclock with 'sudo hwclock -w'
