NEW PRODUCT – Basic GPS module – PMB-648. We picked up a few of these lower-cost GPS modules specifically for those that want to use them for time-keeping purposes. They function perfectly fine as a GPS, but they are not as accurate or low-power as the EM-406 modules we carry for location applications. For that reason, we don’t suggest them for precise, battery-powered location logging.
The PMB-648 GPS features 20 parallel satellite-tracking channels for fast acquisition of NMEA0183 v2.2 data for robotics navigation, telemetry, or experimentation. There is a built-in patch antenna; rechargeable battery for memory and RTC backup; cable for power, TTL and RS-232 connections.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

I picked up one of the old parallax PMB-248 modules Adafruit was stocking before, and like this module, it doesn’t have a pulse per second (PPS) output. If you’re happy with just a serial data stream these will work fine. One of the next project coming up to the head of my queue is going to be a standalone GPS SNTP server if I can get all the code to fit in a ATMega328. I’m really hoping to use the PPS output to narrow in on the exact time. I’m looking at using the EM-406 I have or I’ll get another module with an external antenna option.
