CALYX VS OXA

CALYX — Raspberry Pi HAT+

  • Adds documented 4G/5G cellular to Raspberry Pi designs
  • GPIO modem control, PCM audio and AT commands on official page
  • Suited when the host is Pi-based and a HAT+ form factor is acceptable

OXA — embedded IoT gateway

GermanSTS supports technical selection and sourcing — not firmware development or custom PCB design.

  • OEM/industrial embedded gateway with LTE Cat 4 and Gigabit Ethernet
  • RutOS and documented RMS compatibility
  • Suited when a gateway module with Ethernet uplink and RutOS is required

PHYSICAL INTEGRATION

Cabling, antennas and host wiring alongside module selection.

Embedded projects still depend on correct Ethernet, power and RF cabling — GermanSTS can review connectivity requirements together with module choice.

  • Ethernet and internal data wiring to OXA uplinks
  • Antenna and RF feed planning for cellular modules
  • Power supply and Pi HAT+ mechanical integration for CALYX
  • Industrial cable category where environment demands it

Technical FAQ

Direct answers on selection and scope — without marketing promises.

When should we evaluate CALYX instead of OXA?

CALYX is documented as a Raspberry Pi HAT+ adding 4G/5G with GPIO, PCM and AT command access — suited to Pi-centric prototypes or products. OXA is documented as an embedded IoT gateway with LTE Cat 4, Gigabit Ethernet, RutOS and RMS compatibility — suited when a gateway module with Ethernet and RutOS is required.

Does GermanSTS provide firmware or PCB integration services?

GermanSTS provides technical assessment, interface review and sourcing support for Teltonika hardware. Custom firmware, PCB layout and certification remain the integrator’s responsibility unless separately agreed.

Can CALYX and OXA requirements be reviewed with cabling?

Yes — Ethernet, antenna/feeds and internal wiring questions can be included in the same networking enquiry alongside the model reference.

Embedded capabilities refer to documented Teltonika Networks products. GermanSTS does not manufacture CALYX or OXA.
