Axiometa Genesis Mini

Axiometa Genesis Mini

The Axiometa Genesis Mini is an ESP32ESP32A chipset of microcontroller made/designed by Espressif, used by a number of devices. Higher power usage than nRF52, but often cheaper and supports Wi-Fi if desired.-S3 board with four AX22 module ports. In the Meshtastic build, the LoRaLoRaA low-power, long-range wireless communication technology used by Meshtastic devices to enable communication over distances of several kilometers without the need for cellular, Wi-Fi, or other traditional network infrastructures. radio, the display and the rotary encoder are each a module plugged into one of those ports.

Specifications​

  • MCUMCU (Microcontroller Unit). The microcontroller that runs the firmware on a device. The hardware tables list the MCU for each supported board.
    • ESP32ESP32A chipset of microcontroller made/designed by Espressif, used by a number of devices. Higher power usage than nRF52, but often cheaper and supports Wi-Fi if desired.-S3-MINI-1-N4R2
      • 2.4GHz Wi-Fi, Bluetooth 5 LE
      • 4 MB flash, 2 MB PSRAM
  • LoRaLoRaA low-power, long-range wireless communication technology used by Meshtastic devices to enable communication over distances of several kilometers without the need for cellular, Wi-Fi, or other traditional network infrastructures. Transceiver
    • Elecrow LR1262 module (Semtech SX1262SX1262A Semtech sub-GHz LoRa transceiver, used in most current Meshtastic hardware and recommended over the older SX127x series.)
  • Power
    • Three AA or AAA alkaline cells. The board has no charger, so USBUSB (Universal Serial Bus). The wired connection used to power a device, flash firmware onto it, and communicate with it over serial. powers the node but does not charge the cells.
  • Connectors
    • USBUSB (Universal Serial Bus). The wired connection used to power a device, flash firmware onto it, and communicate with it over serial.-C
    • Four AX22 module ports
    • STEMMA QT (I2CI2CA two-wire bus used to attach peripherals such as sensors and displays to a device.)

Module ports​

The Meshtastic firmware expects each module in a set port:

PortModule
1AX22-0034 display (ST7735S, 160 x 80 IPS)

3AX22-0003 rotary encoder (optional)

The radio and the display are required. Without the encoder, the user button cannot wake a node that has been shut down, and the node needs a reset. A firmware build with different port numbers is needed to use other ports.

Features​

  • 160 x 80 color display with an always-on backlight.
  • Rotary encoder for navigating screens and menus.
  • RGB LEDLED (Light-Emitting Diode). An indicator light on a device. The External Notification module can drive one in response to mesh activity. and user button.
  • No GPSGPS (Global Positioning System). A satellite positioning system. A node with a GPS module determines its own location and can report that position to the mesh..
