The Mecsek Explorer board

Not a relabeled dev kit: we designed this board specifically for CanSat missions, with our own PCB and real space-grade components.

Explore the board in 3D

Rotate, zoom — the same model we use during hardware design.

ESP32-S3

Microcontroller, 240 MHz, 8 MB flash, built-in WiFi

The same architecture used in industrial IoT and robotics products

BMP580

Pressure + temperature sensor

Measures the "pressure proportional to altitude" the CanSat needs — the basis of real rocket/balloon telemetry

AHT20

Humidity + temperature

Environmental data collection, calibration redundancy

TMP102

Secondary temperature sensor

Sensor redundancy — teaches students never to trust a single reading blindly

LSM6DS3

6-axis IMU (accelerometer + gyroscope)

Detects motion, drops, vibration — the mission's "physical" layer

SAM-M8Q

GNSS (GPS) receiver

Track the CanSat's real flight path

E22-900M22S

LoRa radio (SX1262), 868.1 MHz

Real, long-range, low-power radio telemetry — not a WiFi simulation

WS2816B

Status indicator LED

Instant visual feedback on mission state

SD card

Data logging (FAT32)

The mission's full data set is exportable and analyzable — just like a real mission

What a dev kit doesn't give you

The board was designed from our own hardware design documentation, specifically for the CanSat mission profile — not a general-purpose dev board with a new label.

A custom-designed, four-layer PCB

A continuous ground plane and carefully routed signal traces keep the board reliable in a noisy RF and sensor environment — professional hardware-design practice, not hobby electronics.

Stable 3.3V power under any condition

The TPS63001 buck-boost converter keeps the system voltage stable even as the battery's voltage swings — one of the core design challenges in embedded systems.

An expandable, industrial bus system

A CAN interface and a dedicated expansion connector make the board modularly extensible — the same bus system used in automotive and industrial electronics.

Native USB-C programming

The ESP32-S3's native USB peripheral gives driver-free programming and serial connectivity, with ESD protection right at the connector.
