NRF24L01 bụ otu mgbawa transceiver mgbawa na-arụ ọrụ na 2.4-2.5GHz band ISM zuru ụwa ọnụ. Ikuku transceivers gụnyere: Frequency generator Enhanced SchockBurstTM mode controller Power amplifier Crystal amplifier modulator Demodulator mmepụta ike ọwa nhọrọ na protocol Ntọala nwere ike ịtọ site na SPI interface Obere oriri ugbu a, oriri ugbu a bụ 9.0mA mgbe ike nnyefe bụ 6dBm na nnyefe mode, 12.3. mA na ọnọdụ nnabata, na ụdị oriri ugbu a dị ala na ọnọdụ njikere.

Mepee band ISM, nnukwu ike nnyefe 0dBm, ikike iji efu. Na-akwado ọwa isii nke nnabata data

2. Oke ọsọ: 2Mbps, n'ihi obere oge nnyefe ikuku, na-ebelata oke nkukota na nnyefe ikuku (software setịpụrụ 1Mbps ma ọ bụ 2Mbps ikuku nnyefe ọnụego)
3. Multi-frequency: 125 ugboro ugboro iji gboo mkpa nke multi-point nkwurịta okwu na ugboro-hopping nkwurịta okwu.
4. Obere obere: antenna arụnyere 2.4GHz, obere nha, 15x29mm (gụnyere antenna)
5. Oriri ike dị ala: Mgbe ị na-arụ ọrụ na nkwukọrịta ọnọdụ nzaghachi, nnyefe ikuku ngwa ngwa na oge mmalite na-ebelata oke oriri ugbu a.
