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 SPI interface Obere ugbu oriri, The ugbu a oriri bụ 9.0mA mgbe nnyefe ike bụ 6dBm na nnyefe mode, na nke ugbu a oriri na mode na-enweta mode 12.3.

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. Ultra-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.
