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.
