HAMKit VMAC ESP32 has passed EMC to Class B limits.  The Synchronous Buck Converters (for very cool thermal running), also feature an optimised design for Electromagnetic Interference (EMI) reduction. The converter features Frequency Spread Spectrum (FSS) with a switching frequency jitter of ±6%, which reduces EMI by not allowing emitted energy to stay in any one frequency for a significant period of time.

Shipping:

HAMKit include FREE 1st class postage to UK mainland addresses.

International tracked shipping only £10, per order (not including any local taxes).

International Priority Shipping can be provided at an additional cost, on request.
