You’ve seen “long‑range” modules before.
They give you a few fixed pins, a closed firmware, and a prayer that your custom sensor array will fit.
Not this time.
Meet the N532ES-B – the first 31dBm Sub‑1GHz module built around TI’s CC1314R10 that hands you 29 fully usable digital I/O pins, 1MB of Flash, and 256KB of RAM. No compromises. No locked‑down peripherals.
Whether you need to drive a dozen sensors, control relays, read encoders, or run a full TCP/IP stack – this module gives you the pins and the memory to do it.

You don’t have to be an RF engineer. The Skyworks SKY66423 FEM is already matched and tuned for 868/915MHz.
Just power it up and you get:
+27dBm @ 3V / +30dBm @ 4.2V / +31dBm @ 4.8V
8 km line‑of‑sight @ 50kbps (3dBi antenna)
-124dBm sensitivity – hear signals others lose
155dB link budget – punch through walls, trees, warehouses
No tuning. No matching voodoo. It just works.
Most “compact” wireless modules starve you on I/O.
The N532ES-B breaks that rule.
| What You Get | Most Modules | N532ES‑B |
|---|---|---|
| Usable digital I/O | 8–16 | 29 |
| JTAG / debug | often hidden | full access |
| UART / SPI / I²C | fixed assignment | software‑routable |
| Analog inputs | limited | up to 8 |
You can connect multiple sensors, actuators, indicators, and external memory – without playing “pin shortage” games.
The CC1314R10 isn’t a small MCU pretending to be big.
It’s a Cortex‑M4F with:
1MB Flash – hold complex protocol stacks (Wireless M‑Bus, 6LoWPAN, TI 15.4, or your own)
256KB RAM – run real applications, not just “hello world”
OTA update capable – you can actually fit a full firmware image
No more squeezing code into 128KB. No more running out of heap.
Pre‑flashed firmware. Control everything over UART:
That’s it. Works with Arduino, ESP32, STM32, Raspberry Pi.

Use TI Code Composer Studio or IAR.
Access all 29 I/Os, JTAG, peripherals.
Build your own protocol. Run FreeRTOS. Push data at 4Mbps.
You own the firmware – we just give you the certified RF front‑end and the complete pinout.
High power usually means “needs a truck battery”.
The N532ES-B flips that:
RX: 12mA – listen all day
Sleep: <1µA – forget it for months
TX @ 27dBm: 370mA – burst and go back to sleep
Use a 3.7V Li‑ion or a 3.6V Li‑SOCl₂ primary cell.
The CC1314R10’s dedicated radio controller handles the RF while the Cortex‑M4F sleeps.
31 × 21 × 3 mm SMD – pick‑and‑place ready
IPEX + stamp hole antenna – use PCB trace or external whip
4‑layer PCB – 50Ω impedance, industrial noise immunity
Industrial temp: -30°C to +75°C
Separate PA supply – 2.3V to 5.5V, optimize for your battery chemistry
| Application | Why It Fits |
|---|---|
| Smart Agriculture | 8km range across fields, 29 I/Os for soil sensors + pump relays |
| Utility Metering | Punch through concrete basements, 1MB Flash for secure firmware |
| Industrial SCADA | 31dBm cuts through factory noise, 256KB RAM for data logging |
| Medical Telemetry | Low power, patient‑safe range, JTAG for certified firmware |
| Smart City | One gateway covers a district, 29 I/Os for multi‑sensor poles |
For gateways, pair it with the N537EP USB dongle – same CC1314R10, +27dBm, plug‑and‑play.
