T1000-E Card Tracker is a thin, credit card-sized GPS tracker with Meshtastic support

Seeed Studio has introduced the T1000-E, an updated version of the SenseCAP T1000 Card Tracker, built for Meshtastic. This rugged tracker is compact, about the size of a credit card, making it easy to carry or attach to assets. It uses Semtech LR1110 RF transceiver, Nordic Semi nRF52840 wireless SoC, and MediaTek/Aihora AG3335 GPS module for precise, low-power tracking and communication. With an IP65 rating for dust and water resistance, the T1000-E is ideal for reliable asset tracking.

The T1000-E supports LoRa and Bluetooth v5.1 for communication and includes a 3-axis accelerometer, an LED, a buzzer, and a button for operation. It has internal antennas for GNSS, LoRa, Wi-Fi, and BLE communication range of 2 to 5 km, depending on the environment.

The T1000-E tracker includes four pogo pins that offer USB support for DFU (Device Firmware Upgrade), serial logging, and API access, simplifying device management and debugging. More details about the hardware and firmware can be found on the wiki page. It is also compatible with the Meshtastic open-source firmware that implementation a mesh networking protocol for long-range, low-power messaging and GPS coordinate sharing.

Meshtastic is a free, open-source, decentralized mesh network that uses LoRa radios to establish a low-power, long-range, off-grid communication system in areas without reliable infrastructure. Driven entirely by the community, Meshtastic enables decentralized, encrypted communication without the need for a dedicated router or phone. The Meshtastic mobile app is available on both Android and iOS platforms.

Previously, we covered other GPS trackers like the Seeed Studio Wio Tracker 1110, Wio LTE GPS Tracker, Wio GPS Tracker, and the S5 Trekker. Feel free to check them out.

The SenseCAP Card Tracker T1000-E for Meshtastic is available for purchase on Seeed Studio for $39.90 and includes a 1-meter USB charging cable.
