Quectel SRG091X and SRG093X NXP i.MX 9 industrial AIoT modules integrates Wi-Fi 6, Bluetooth 5.4, and 802.15.4 radios

Quectel SRG091X and SRG093X NXP i.MX Smart AIoT module

After releasing the very powerful P895BD-AP AIoT module at CES 2026, Quectel now released two new low-power industrial AIoT modules based on NXP’s i.MX 9 series SoCs. The module integrates Wi-Fi 6, Bluetooth 5.4, and 802.15.4 radios through the IW610G chipset, so it can simply be dropped into a PCB to create a fully compliant Matter Border Router without any RF design or coexistence concerns. While both modules share the same 46 x 41.5 mm form factor and wireless capabilities, they are different in terms of CPU power as the SRG091X is an entry-level solution built around a single-core NXP i.MX 91 processor, while the SRG093X features dual-core NXP i.MX 93 SoC, which includes a Cortex-M33 real-time core and a neural processing unit (NPU) for edge AI workloads. The module supports LPDDR4/LPDDR4X memory, eMMC storage, and various I/O options, including dual Gigabit Ethernet, USB 2.0, CAN-FD, SPI, UART, I²C/I³C, ADC, […]

Quectel SP895BD-AP AIoT module features Qualcomm Dragonwing Q-8750 SoC with 80 TOPS NPU

Just yesterday, we wrote about the Qualcomm Dragonwing Q‑7790 and Q‑8750 AIoT SoCs, and on the same day, Quectel launched the SP895BD-AP smart AIoT module based on the Dragonwing Q-8750. It is designed for high-performance IoT applications, including video conferencing, 8K computing power boards, and smart retail terminals, running on Android 15 or Linux. Earlier in November, we saw Qualcomm introduce the Dragonwing IQ-X series of SoCs for industrial PCs running Windows. The Q-8750 in the Quectel SP895BD-AP seems to be a variant of the high-end version, with an 8-core Oryon CPU (up to 2x 4.32 GHz + 6x 3.53 GHz) and an Adreno Series 8 GPU. It supports 8K video encoding and decoding with three ISPs for up to 3×48MP camera inputs, or a single camera input of 108MP. The module comes in a compact LGA package and supports standard interfaces like MIPI DSI/CSI, PCIe, USB, I2S, UART, I²C, […]
