N532ES-B: 29 Fully Customizable I/Os, 1MB Flash, and 31dBm – The CC1314R10 Module That Puts You in Control

🧠 You Want Power. You Want Range. You Want Freedom.

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.

⚡ The “Just Works” RF Part – 31dBm, 8km, -124dBm Sensitivity

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.

🧩 29 I/Os – Yes, Twenty‑Nine. Not 12. Not 16.

Most “compact” wireless modules starve you on I/O.
The N532ES-B breaks that rule.

You can connect multiple sensors, actuators, indicators, and external memory – without playing “pin shortage” games.

💾 1MB Flash, 256KB RAM – Finally, Enough Headroom

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.

⌨️ AT Commands? Or Full SDK? Your Choice.

Option A – Zero‑Code Mode (AT Commands)

Pre‑flashed firmware. Control everything over UART:

AT+SCAN=868000000
AT+SEND=Hello
AT+RSSI?

That’s it. Works with Arduino, ESP32, STM32, Raspberry Pi.

Option B – Full Custom Firmware

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.

🔋 Ultra‑Low Power – Because 31dBm Shouldn’t Kill Your Battery

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.

📦 Hardware That Doesn’t Fight You

• 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

🌍 Where Engineers Use the N532ES‑B

For gateways, pair it with the N537EP USB dongle – same CC1314R10, +27dBm, plug‑and‑play.
